KIT-HYD CYLINDER SEAL 3812331 - Caterpillar

General Functional Test Information
Following installation, the standby electric system installation should be inspected, and tested. All necessary adjustments should be completed. Functional testing of the transfer switch consists of (1) manual operation, (2) voltage checks, and (3) electrical operation.
Perform functional tests in the exact order given, to avoid damaging the transfer switch.
Read and make sure you understand all instructions in this section before proceeding with the functional tests. Also read all instructions and information on tags and decals that are affixed to the transfer switch. Note any options or accessories that might be installed or provided with the switch and review their operation.Manual Operation
Do not attempt manual operation of the transfer switch until both power supplies have been positively turned OFF, using whatever means provided (such as the normal and standby source main line circuit breakers). Failure to turn OFF all power voltage supplies to the transfer switch may result in extremely hazardous, and possibly lethal, electrical shock.
A manual handle and an actuating pin are shipped with the transfer switch. Manual operation must be checked before the switch is operated electrically. To operate the switch manually, proceed as follows:
Do not use excessive force when actuating the main contacts manually, or the manual handle may be damaged. Always set the contacts to their TRIPPED or NEUTRAL position before manually selecting either NORMAL or STANDBY. The switch is at TRIPPED or NEUTRAL when the word "OFF" appears in both windows "A" and "B".
1. Turn OFF both the NORMAL and STANDBY power supplies to the transfer switch.2. Note the position of the transfer mechanism main contacts by observing the display in Windows "A" and "B", as follows:* Window "A" indicates "ON" - Load terminals (T1, T2, T3) are connected to the normal terminals (N1, N2, N3)* Window "B" indicates "ON" - Load terminals (T1, T2, T3) are connected to the standby terminals (E1, E2, E3)* Windows "A" and "B" both Indicate "OFF" - This is the tripped or neutral position, with both power sources disconnected from the load terminals.3. If the word "ON" is visible in either window "A" or "B", first trip the switch (set to NEUTRAL) as outlined in Step (4). Always trip the switch (set to NEUTRAL) before closing the switch to either Position "A" or "B". The switch is tripped if the word "OFF" appears in both windows "A" and "B". If the switch is already TRIPPED or at NEUTRAL, go to Step (5). 4. To trip the Switch - This is the NEUTRAL position, with both power sources disconnected from the load. Use the operating pin (shipped with unit) to push in on trip lever in Hole "T" (located on top of the transfer mechanism). The main contacts should trip and the word "OFF" should appear in both windows "A" and "B". 5. To close "A" - Attach the manual handle to square shaft at upper left corner of Transfer Mechanism. Move the handle upward. The word "ON" should appear in window "A" ("OFF" in window
