1. DESCRIPTIONThe BA578E is a general purpose, panel mountinginstrument with two inputs that can be configuredon-site as a Timer or as a Clock.

As a Timer the BA578E can measure and displaythe elapsed time between external events, or controlexternal events via the status output or optionalcontrol outputs.

When configured as a Clock, the instrument candisplay time in a variety of formats and the optionalcontrol outputs may be configured to turn on and offat pre-set times.

This instruction manual is divided into threesections.

This instruction manual supplements theabbreviated instruction sheet supplied with eachinstrument.

2. SYSTEM DESIGNFig 1 illustrates the basic circuit that is used for allBA578E Timer installations. BA578E Clockinstallations are the same, except that the two inputterminals are not used. For simplicity the statusoutput and the optional control outputs aredescribed separately in sections 2.4 and 2.5 of thismanual.

Fig 1 BA578E connections

2.1 Power supplyThe BA578E requires a supply of 10 to 30V dcbetween terminal 1 & 2 and consumes:

10mA without optional backlightplus 16mA for optional backlightplus 6mA when terminals 3 & 4 are linkedplus 6mA when terminals 7 & 8 are linked

2.2 Sensor inputsWhen configured as a Timer both inputs may beconnected to a wide variety of sensors as shown inFig 1. The two BA578E inputs are not used whenthe instrument is configured as a Clock.

The following table shows the instrument's inputswitching thresholds when configured to operatewith various sensors. For reliable operation theBA578E input must fall below the lower thresholdand rise above the upper threshold.

6

SensorSwitching thresholds

Lower Upper

Switch 100Ω 1000Ω

Proximity detector 1.2mA 2.1mA

Open collector 2kΩ 10kΩ

Magnetic pick-off 0 40mV peak

Voltage pulse low 1.0V 3.0V

Voltage pulse high 3.0V 10.0V

Switch contacts, proximity detectors and opencollector sensors require energising which isachieved by linking two BA578E terminals togetherfor each input, see Fig 5.

2.2.1 Switch contact inputAny switch contact may be directly connected toinput terminals 5 & 6 or 9 &10. The BA578Econtains a separate configurable debounce circuitfor each input to prevent false triggering. Threelevels of debounce protection are available Seesection 5.5.6.

2.2.2 Open collector inputAny sensor with an open collector output such as aopto-isolator may be directly connected to inputterminals 5 & 6 and 9 &10.

2.2.3 2-wire proximity detector inputMost NAMUR 2-wire proximity detectors may beconnected to a BA578E input, providing theminimum operating voltage of the proximity detectoris less than 7.5V. The BA578E contains a separateconfigurable debounce circuit for each input toprevent false triggering. Three levels of debounceprotection are available See section 5.5.6.

2.2.4 Magnetic pick-off input CoiL in the input configuration menu is a low levelvoltage pulse input intended for use with a magneticpick-off sensor. The BA578E contains a separateconfigurable debounce circuit for each input toprevent false triggering. Three levels of debounceprotection are available See section 5.5.6.

2.2.5 Voltage pulse inputTwo voltage pulse input ranges are independentlyselectable for each input in the BA578E Timerconfiguration menu, VoLt5 L and VoLt5 H allowingalmost any sensor with a voltage output to be used:The BA578E contains a separate configurabledebounce circuit for each input to prevent falsetriggering. Three levels of debounce protection areavailable See section 5.5.6.

2.3 Remote resetConnecting the external reset terminals RS1 andRS2 together will reset the BA578E when configuredas a Timer and synchronise the displayed time to apreset time when configured as a Clock.

Note: When used as a Timer the BA578E may alsobe reset from the display mode by operating the &

and * push buttons simultaneously for more thantwo seconds. See 5.5.20

2.4 Status outputAll BA578E instruments have an opto-isolated opencollector output which can be configured to indicatethe status of the instrument, or to perform simplecontrol functions. The output has the followingelectrical parameters:

Ron = 60Ω + 3VRoff = 1MΩImax = 10mA

The status output is a passive circuit i.e. un-poweredopen collector, but it is totally isolated from all othercircuits. Terminals P1 and P2 may be connected toanother instrument that can accept an open collectorinput.

Fig 2 shows how the status output may be used toproduce a voltage output.. The positive terminal ofthe status output P1 is connected to the instrument’spositive supply terminal 1. When the status opencollector output is activated, the voltage on terminalP2 rises to the supply voltage less 3V and a currentflows through the resistor R1. This current isdefined by R1 which should be chosen to limit thecurrent to less than 10mA. For a 24V supply R1should be greater than 2,200Ω.

2.5 Control outputs (optional)Each of the two factory fitted optional control outputsis a galvanically isolated single pole solid stateswitch as shown in Fig 3. The outputs are polarisedand current will only flow in one direction. TerminalsA1 and A3 should be connected to the positive sideof the supply.

Note: Because of the series protection diode sometest meters may not detect a closed alarm output.

Fig 3 Equivalent circuit of each control output

The solid state output of each control output may beused to switch any dc circuit with parameters of:

V max = 30VI max = 200mA

Fig 4 Typical control output application

3. INSTALLATION

3.1 LocationThe BA578E has a robust glass reinforced Norylenclosure with a toughened glass window. The fronthas IP66 ingress protection and a gasket seals thejoint between the instrument enclosure and thepanel, the rear of the instrument has IP20 ingressprotection.

The BA578E may be installed in any panel providingthat the operating temperature is between -40°C and+70°C. At temperatures below -20°C the displaydigits will change more slowly and the contrast willbe reduced, but the instrument will continue tofunction

Fig 5 shows the overall dimensions of the instrumenttogether with the recommended panel cut-outdimensions. To achieve an IP66 seal between theinstrument enclosure and the instrument panel thesmaller tolerance aperture must be used, and theinstrument must be secured with four panelmounting clamps.

Although the front of the BA578E has IP66protection it should be shielded from continuousdirect sunlight and severe weather conditions.

3.2 EMCThe BA578E complies with the requirements of theEuropean EMC Directive 2014/30/EU. For specifiedimmunity all wiring should be in screened twistedpairs, with the screens earthed at one point.

3.3 Installation Procedure

a. Cut the specified aperture in the panel. Toachieve an IP66 seal between the instrumentenclosure and the instrument panel theaperture must have the tighter tolerancesspecified in Fig 5.

b. Slide the gasket over the body of the BA578Ebefore inserting the instrument into the panelaperture.

c. Firstly ensure that all the panel mountingclamps are closed by turning the knurledscrews fully anti clockwise until the two pips inthe clamp foot align with holes in the clampbody.

d. Place a clamp in the recess on each side of theinstrument, pulling gently to slide it onto thedovetail as shown in Fig 6. Push the knurledscrew slightly forward to engage the thread andtighten by turning clockwise until it is just fingertight. When the clamps are fitted ensure thatthe gasket behind the front panel bezel iscorrectly positioned before fully tightening theclamps to secure the instrument. The maximumrecommended clamp tightening torque is22cNm (1.95 lbf in) which is approximatelyequivalent to finger-tight plus one half turn.Do not over tighten.

e. Four panel mounting clamps are required toachieve an IP66 seal between a BA578E andthe instrument panel.

f. Connect the panel wiring to the rear terminalblock(s) as shown in Fig 5. To simplifyinstallation, the terminals are removable so thatthe panel wiring can be completed before theinstrument is installed. In areas subject tovibration wiring should be secured to preventdamage to the connectors.

3.4 Scale cardThe BA578E's units of measurement are shown ona printed scale card visible through a window at theright hand side of the display. The scale card ismounted on a flexible strip that is inserted into a slotat the rear of the instrument as shown in Fig 7.Thus the scale card can easily be changed withoutremoving the BA578E from the panel or opening theinstrument enclosure.

New instruments are supplied with a printed scalecard showing the requested units of measurement, ifthis information is not supplied when the instrumentis ordered a blank card will be fitted.

A pack of self-adhesive scale cards printed withcommon units of measurement is available as anaccessory from BEKA associates. Custom printedscale cards can also be supplied - see 4.3

To change a scale card, unclip the tapered end ofthe flexible strip at the rear of the instrument bygently pushing it upwards and pulling it out of theenclosure. Peel the existing scale card from theflexible strip and replace it with a new printed card,which should be aligned as shown below. Do not fita new scale card on top of an existing card.

Install the new scale card by gently pushing theflexible strip into the slot at the rear of theinstrument, when it reaches the internal end-stopsecure it by pushing the end of the flexible stripdownwards so that the tapered section is held by therear panel.

Align the self-adhesive printedscale card onto the flexible stripand insert the strip into theinstrument as shown below.

4.2 Control outputsAlthough the dual isolated control outputs arefactory fitted options, they are described in the mainbody of this instruction manual as they will be usedfor the majority of applications – see section 2.5. Ifcontrol outputs are required they should be specifiedwhen the instrument is ordered.

4.3 Scale cardThe BA578E has a window on the right hand side ofthe display through which a scale card showing theunits of measurement such as hours can be seen.New instruments are fitted with a scale card showingthe units of measurement specified when theinstrument was ordered, if the units are not specifieda blank scale card will be fitted. A pack of scalecards pre-printed with common units ofmeasurement is available as an accessory. Thesecan easily be fitted on-site to the BA578E withoutopening the instrument enclosure or removing itfrom the panel. See section 3.4 of this instructionmanual.

Custom scale cards for applications requiring lesscommon units of measurement are also available.

5. OPERATION AS A TIMERWhen configured as a Timer the BA578E canmeasure and display the elapsed time betweenexternal events. The Timer can be started andstopped by remote sensors, or from the front panelpush buttons.

The addition of optional factory fitted isolated controloutputs allows the Timer to control external eventssuch as opening a valve for a predetermined time.Again the Timer can be started and stopped byremote sensors, or from the front panel pushbuttons. Timed events can be repeated using theCYCLE function which enables the BA578E Timer torepeat the timing period up to 99 times, orcontinuously, with a configurable delay betweentimed periods of up to 100 hours.

The BA578E may be configured to time-up fromzero to the set time 5Et t, or to time-down from theset time to zero. Times may be entered anddisplayed in hours, minutes or in seconds, or in acombination of units. Elapsed or remaining time iscontinuously displayed and a separate display maybe activated to show the target set time 5Et t.Throughout the timing cycle the instrument can bepaused and restarted without changing the cycletime. Resetting is accomplished via the front panelpush buttons or a remote contact.

A grand total time is maintained by the instrumentwhich can be viewed by operating the front panelpush buttons and reset from the display mode orfrom within the configuration menu.

Fig 8 shows a simplified block diagram of theBA578E when configured as a Timer. The twoseparate inputs A and b can be individuallyconfigured to accept inputs from a wide variety ofsensors. When the sensor requires energising todetect its state, such as a switch contact, opencollector or a two wire proximity detector, a linkconnected between external terminals of theBA578E supplies power to the sensor inputterminals.

The optically isolated open collector status output isintended for monitoring the Timer's status, but mayalso be used for simple control applications.

The instrument can be supplied with the followingfactory fitted accessories:

Internally powered Backlight

Dual isolated Control Outputs

The optional factory fitted dual isolated solid statecontrol outputs may be independently configured tobe activated in any of the timer's state allowing theBA578E Timer to perform a wide variety of tasks.

5.1 InitialisationEach time power is applied to a BA578Einitialisation is performed. After a short delay thefollowing display sequence occurs:

All segments of the display are activated

BA578E is ready to start functioning usingthe configuration information stored in theinstrument's permanent memory.

5.4 Timer structureFig 9 illustrates the Timer structure and function as astate diagram. It applies when the instrument ismeasuring the time between events or is controllingexternal events.

The circles in Fig 9 represent the five Timer states,Reset, Running, Restart-delay, Paused andComplete. The lines between the circles representthe event required to move the Timer betweenstates. e.g. to initiate timing the Timer is movedfrom the Reset state to the Running state by a startevent. This could be an input signal at input A oroperation of the & button. Similarly, to pause theTimer while it is timing, the Timer must be movedfrom the Running state to the Pause state by a stopevent which could be an input on input b oroperation of the * button.

ResetIn this state the Timer is readied for operation.The Timer is stopped and loaded with zero fortiming-up or 5Et t for timing-down.

RunningEntered by a start event from the Reset orPaused states. The Timer times-up to 5et t

or times-down to zero depending upon it'sconfiguration.

PauseEntered by a stop event from Running orRestart-delay. Timer is stopped, a start eventreturns the timer to it's previous state.

Restart-delayEntered automatically from Running. At theend of the delay time automatically returns toRunning.

CompleteEntered automatically from Running whenthere are no more timing cycles to perform.

When the CYCLE5 function is enabled the timingcycle can be specified to repeat up to 99 times, orcan be configured to repeat continuously.

In this example a BA578E is required to display thetime that a process area contact is closed. Thedisplay is required in hours and minutes and is to bereset to zero by an exterior push button, not by theinstrument front panel push buttons. The operatoris required to zero the grand total by operating the) + * buttons simultaneously. No securitycodes are required to protect access to theconfiguration menu or to the grand total reset.

Figure 11 shows the BA578E connections. Thisexample illustrates how the Timer may be startedand stopped by one input, the second input is notused in this application.

6.2 Controlling a solenoid valveThis example illustrates how a BA578E Timer canopen a solenoid valve for 5 minutes each time astart button is operated. The operator needs topause the process without affecting the total timethat the valve is open. At the end of the process theTimer is required to automatically reset within 10seconds ready for the next timing cycle to bestarted.

For this application the BA578E Timer requires dualcontrol outputs which are a factory fitted option andshould be specified when the instrument is ordered.

Control output 1 is used to switch the intrinsicallysafe solenoid valve, and control output 2 is wired tothe Timer's reset terminals to perform the automaticresetting at the end of the timing cycle, see Fig 12.

The Timer is configured to perform one timing cyclecycl cnt with a restart delay r5t dela of 5s and Settime 5et t is adjusted to 5 minutes the required timethat that the valve is to be open.

Control outputs are configured so that control outputone is only closed when the timer is in the Run state.Control output 2 is configured to only close when theTimer is in the Done state which occurs after it hasbeen in the Restart-delay state for 5 seconds. Thesequence of events is shown in Fig 12 and theTimer's configuration at the end of this section.

This valve opening process is to be linked to otherprocesses, therefore the status output is required toindicate when the 5 minute valve open period hasbeen completed and when the Timer has been resetand is ready for the next cycle.

When the start button is operated the Timer entersthe Running state and control output 1 closes for 5minutes opening the solenoid valve. At the end ofthe 5 minute period control output 1 opens whichcloses the solenoid valve and the Timer enters theRestart-delay state for 5 seconds followed by theDone state. Control output 2 is configured to closewhen the Timer is in the Done state. Control output2 is externally connected to the Timer's resetterminals which causes the Timer to automaticallyreset ready to start another cycle when the startbutton is operated.

If at any time during the cycle the stop button isoperated the Timer will enter the Pause state whichwill stop the process until the start button is operatedwhen it will resume without shortening the total valveopen time.

8. OPERATION AS A CLOCKWhen configured as a clock the BA578E can displaylocal time in a variety of twelve or twenty four hourformats. The displayed time can be adjusted viathe front panel push buttons which may be protectedby a user definable four digit security code toprevent unauthorised or accidental adjustment.

The clock may be synchronised to an external timestandard via the instrument's reset terminals. Whenthese two terminals are connected together by anexternal switch contact, the clock display will bereset to a preconfigured time and will resumerunning from this time when the contacts areopened.

The optically isolated status open collector outputcan be used to monitor the clock or to performsimple control functions.

When fitted with the optional galvanically isolatedcontrol outputs the clock can be configured to turneach solid state output on and off twice during eachtwenty four hour period.

Fig 13 shows a simplified block diagram of theBA578E configured as a clock.

The instrument can be supplied with the followingfactory fitted accessories:

Backlight Internally powered

Dual isolated control outputs

Fig 13 BA578E block diagram with clock configuration.

8.1 Initialisation and loss of powerEach time power is applied to a BA578Einitialisation is performed. After a short delay thefollowing display sequence occurs:

All segments of the display are activated

Instrument starts functioning, using theconfiguration information stored in theinstrument's permanent memory.

Following initialisation, the instrument will have aflashing display which is a request for the local timeto be entered. The clock will not start to functionuntil a display time has been entered, or the remotereset contacts are closed and opened tosynchronise the clock to a preconfigured time.

If during normal operation the power supply isinterrupted for more than 30ms, the display willreturn to the flashing condition and the display timewill have to be re-entered. This time may beincreased by powering the Clock from a lightlyloaded instrument supply with large outputcapacitance.

8.2 Controls when configured as a clock The BA578E clock is configured and adjusted viafour front panel push buttons. In the display modei.e. when the instrument is displaying time, the pushbutton functions are:
