3. Special Maintenance Instructions

Lever (37)

As stated in the figure the lever (37) has to be fixed to 13,2 mm in the position “closed” of the final control element ofthe pilot control stage. Readjustment is to be made by the adjusting screw at the piston (50).

Note: The adjustment has to be secured via the locking nut (51).

+ 0,3

Connection between lever (37, 54) and lever loop (14, 27, 106, 109, 121)

• In order to connect the final control element and the actuator the lever loop (14, 27, 106, 109, 121) of the pre-mounted diaphragm units has to be pushed laterally above the cylindrical end of the lever (37, 54). It is advantageous to use an adjusting tool (e. g. a screw driver) that keeps the lever (37, 54) at a highest possible position.

• The connection between lever and lever yoke is adjusted by turning the diaphragm clockwise and counter-clockwise to the stops to find the central position.

Sealing washer (114)

• The bore of the sealing washer should not be oval. (The sealing washer has no absolut leakage protection function)

• The sealing washer (114) must smoothly move in transverse direction in its support ring.

Spring housing (31, 60)

Easy mounting of the spring housing (31, 60) in the intermediate pressure stage of the preadjusted springs is given by the additional length of two screws (25) of approximately 10 mm. These screws must be inserted in the two thread boringsthat are located in a special angle of 90° to the axle of the appliance.For dismantling the two longer screws are to be loosen at last.

Setpoint Adjustments

The setpoint value increases by turning the setpoint adjustment screws (1), (101) clockwise. After a setpoint changing the setpoint adjuster has to be secured via the following elements:

intermediate pressure stage flat head screw (61) pilot control stage flat head screw (61) safety relief valve for gas leakages in control stage nut (100).

The changing of the setpoint is impossible for the safety relief valve of the intermediate pressure stage.

201.20 p.14

Every person engaged with installation, supervision, or maintenance of the gas pressure regulator type HON 201 is requested to read the following leaflets and brochures beforehand:

- Technical Description 201.00 - contains technical data, measurements, and describes function and design.

- General Operating Instructions for Gas Pressure Regulators and Safety Devices - this Honeywell brochure describes installation and operation, and includes general hints on fault finding and repair.

- Operation and Maintenance, Spare Parts 201.20 - contains further details on installation and operation of the gas pressure regulator HON 201.

Additionally, the relevant national rules and laws have to be strictly observed. (In Germany please refer to the DVGW worksheets G 490, G 491 and G 495).

The frequency of periodical maintenance of the gas pressure regulator HON 201 should be determined according to the prevailing conditions and the type and composition of the gaseous medium. Therefore, no fixed maintenance intervals can be prescribed. For Germany: At the beginning we recommend to use the maintenance intervals stated in the DVGW worksheet G 495. Then individual maintenance intervals should be determined for every station. For maintenance all parts are to be cleaned and subjected to a thorough visual inspection. A visual inspection should also occur when the course of operation or functional tests have shown lack of regulating accuracy. Particular care should be given to the checking of sealings and diaphragms, as well as carrying and moving parts. Damaged parts should be replaced by new ones. The item numbers referred to in the maintenance instructions are identical with those of spare parts drawings and spare parts lists.

We recommend to keep all parts that are specially marked "W" in the spare parts lists in stock for prompt maintenance availiability.
