A. Tools and consumable materials
- 2 isolating valves
ABAB
Validity : Electrohydraulic generator "L.H.C." 32-35-0 Page 204
1 (CA) JUN 01
 
- 1 pressure gage
- 1 three-way union
- 3 high pressure pipes
- 1 battery 24 volts or constant voltage electric supply
- Electric wiring
- 1 ammeter
- 1 voltmeter
- 1 control switch
- Hydraulic fluid (TB 02-001)
B. Procedure
1) Remove the electrohydraulic generator - refer to Paragraph 2.
2) Connect the electrohydraulic generator according to Figure 202.
3) Open the two isolating valves and run motor in both directions to purge air from test system.
4) Close isolating valve (8). Run motor to check high pressure and electric consumption - see charts hereafter.
5) Run motor to the low pressure direction. The pressure has to reach zero.
6) Close isolating valve (6). Open isolating valve (8). Run motor to check low pressure and electric consumption - see charts hereafter.
7) Run motor to the high pressure direction. The pressure has to reach zero.
NOTE : If the recommended pressures are not reached, replace the corresponding valves.
