If the procedure outlined in Section V (MAINTENANCE)
fails to restore proper operation, it is recommended that the
relay be returned to the factory for repair due to the critical
orientation of the components. Contact the factory or a factory
representative for instructions on returning the relay.
If the relay is to be repaired in the field the order in which the
plates and gaskets were assembled, and the orientation of those
parts, must be noted so that they may be reassembled correctly.
Repair kits are available as specified below.
To repair the relay, disassemble the relay as shown in Figure 4
(except as noted) and follow the instructions below:
1. Inspect air passages for dirt.
2. Inspect the Valve (18) surfaces for bumps, scars or other
irregularities. The Hemispherical Surfaces (C in Figure
3) must be smooth and regular.
3. Inspect the Valve Seats (A and B in Figure 3). The
surfaces must be clean and smooth with no scars or
surface irregularities.
4. Inspect Diaphragms (29 for holes or worn spots which
might permit air leakage.
5. Install the Valve (18), Valve Spring (19) and Spring
Retainer (20) and make sure that the Valve Spring (19) is
seating the Valve (18) properly.
6. Replace any worn or defective parts and reassemble the
relay.
DO NOT USE ANY GASKET SHELLAC, PIPE
COMPOUND, OR OTHER SEALANT.
7. With Supply and Input air pressures connected, check the
unit for external leakage.
8. Follow procedure in Section IV (ADJUSTMENTS).
CAUTION: If cleaning is required, do not subject the
Diaphragms or Gaskets to cleaning fluids or solvents.
