Design in switchboard IP65

Application

Function

The automatic standby unit (hereinafter referred to as ZA) is used to provide power supply without any long-term blackouts in various sectors of services, industry, etc.

The automatic standby unit ensures automatic and, above all, safe control of switching of two power supplies to twoloads so that the electric power is supplied without long failures.The automatic standby unit is designed for collaboration with circuit breakers/switch-disconnectors Modeion and ArionWL, which ensure power switching. For detailed information on circuit breaker/switch-disconnector fitting see page 10.The power supplies can be switched over by a failure of one or more phases, undervoltage or overvoltage of the powersupplies. The automatic standby unit enables the control (switching on/off) of the backup power supply (generator).

Control and settingBasic functions of the automatic standby unit are selected by a rotary switch on the front panel, and additionalsettings (modes and reaction times) are setby means of control panel.

display informing the operator about immediate state of circuit breakers, power supplies and actuallyperformed action.

ouch display for setting the parameters for automatic control of the standby mode. Example: reactiontimes (for detailed information see Table of Specifications on page 10), automatic standby mode (seefunctions and setting on page 15 - 16) or security password, which protects the automatic standby unitagainstunauthorized resetting.

otary switch for setting of 4 basic functions of the automatic standby unit(for detailed description see"functions and setting" on page 15 and 16).

he user can use undervoltage relays (only for design ZA-xx-xx1x) to set the values of undervoltage orovervoltage (independently of each other) to be evaluated by theautomatic standby unit as a power supplyfailure with taking an appropriate action.

here is a screw terminal block for connection of individual conductors, which connect the automatic unitwith circuit breakers/switch-disconnectors.

c) Every automatic standby unit includes terminals for connection of the STOPbutton (terminals 30 and 31).

d) Every automatic standby unit includes terminals for connection of the inspection button (terminals 40 and41). The inspection button serves for possible checks on instruments. If no mechanical interlocking isinstalled, it is necessary to beware of a parallel run. The inspection button will disable the control unitoperation and will supply power to the under-voltage releases, see the wiring diagram. If the sheet-steelcover is used, the inspection button is already included and is connected.

The arrangement of circuit breakers/switch-disconnectorsand their connection to the automatic standby unitThe arrangement of circuit breakers (a distance between them) isnot limited in any way. If mechanical interlocking is used to increasesafety in manual control, the distance between the circuitbreakers/switch-disconnectors is given by the used mechanicalinterlocking.

Functions switchSwitchboard IP65

Advantages:The display of the automatic standby unit informsthe operator of the immediate state of circuitbreakers, power supplies and actually performedaction.

The automatic standby unit is protected againstunauthorized resetting by the password.

Safety

Power supply

The circuit breakers/switch-disconnectors are electrically interlocked by means of the automatic standbyunit so that in no case both the power supplies can be switched on simultaneously. To increase safety inmanual control it is possible to complete the circuit breakers/switch-disconnectors by mechanicalinterlocking.

The automatic standby unit must be supplied either from controlled power supplies (or from a momentarilyactive one) or from an independent external power supply such as UPS or AKU. The function of theautomatic standby unit depends in some cases on the power supply Metod (see time diagrams on page 17 -19).

STANDBYFOR BOTH POWER SUPPLIES

STANDBYFOR 1 POWER SUPPLY

STANDBYFOR 2 POWER SUPPLY

Both loads can be supplied permanently from any power supply. In case of loss of voltage of the power supply theload is supplied from the load, the load is disconnected from the power supply and connected (via coupling closing)to 2 power supply. After voltage renewal of the original power supply the coupling opens, and the load isconnected to the original power supply.

The load 1 can be supplied from the power supply 1 or the power supply 2, the load 2 can only be supplied fromthe power supply 2. In case of loss of voltage of the power supply 1, the load 1 is disconnected from the powersupply 1, and connected to the power supply 2 (via coupling closing).After voltage renewal of the power supply 1the coupling opens and the load 1 is connected to the original power supply. In loss of voltage of power supply 2the load 2 will remain without voltage for the time of the loss of voltage of power supply 2, no standby will takeplace.

The load 2 can be supplied from the power supply 2 or the power supply 1, the load 1 can only be supplied fromthe power supply 1. In case of loss of voltage of the power supply 2, the load 2 is disconnected from the powersupply 2, and connected to the power supply 1 (via coupling closing). After voltage renewal of the power supply 2the coupling opens and the load 2 is connected to the original power supply. In loss of voltage of power supply 1 theload 1 will remain without voltage for the time of the loss of voltage of power supply 1,no standby will take place.

FUNCTION, SETTING

Setting of undervoltage relays nly design ZA-xx-xx1x(o )The automatic standby unit monitors the level of voltage of power supplies, power failures and phase sequence by means of undervoltage relays. On these relays it ispossible to set the overvoltage / undervoltage level, to which the automatic standby unit shall react within the range + 30 %/ -20 %; in case ofensuring permanent powersupply of the system from 2 or standby power supply, it is possible to set the tolerance of the monitored voltage at +/- 30 %. Delay of making of the undervoltage relaycontact is set by the manufacturer and cannotbe changed.
