Remote monitoring functions are only available with the AUTO/OFF/MANUAL switch in the Auto or Manual position. Since the contacts are SPDT, it is possible to monitor either state of each alarm function.

Relay 1: Engine running, normally closed.

Engine not running, normally open

‹2.1.3 TRANSFER SWITCH CONNECTION

These switches (Figure 2.3) are used with a single- phase system, when the single-phase NEUTRAL line is to be connected to a Neutral Lug and is not to be switched.

Relay 2: Transfer Switch in Emergency, normally closed

Transfer Switch in Utility, normally open

Relay 3: Control panel switch in Auto, normally open

Control panel switch in Manual or Off, nor- mally closed

Relay 4: The common alarm is activated by any of the following shutdown faults

Low Oil Pressure

High Engine Temperature Overspeed

Overcrank

Common alarm active, normally open No Common alarm, normally closed

Relay 5: Spare, not used on this model

Relay 6: Enclosure door open, normally closed

Enclosure door closed, normally open

This generator is equipped with an alarm to detect when the roof of the enclosure is open. A limit switch that is installed in the generator enclosure controls this alarm. During shipping, the generator's enclosure panels may have shifted and this limit switch may require adjustment. Simply loosen the two screws and adjust the placement of the limit switch. The arm of the limit switch should be in the depressed posi- tion when the enclosure roof is closed and the door latch is secure (see Figure 2.2).

Conductor sizes must be adequate to handle the maximum current to which they will be subjected to, based on the 75°C column of tables, charts, etc. used to size conductors. The installation must comply fully with all applicable codes, standards and regulations.

Before connecting wiring cables to terminals, remove any surface oxides from the cable ends with a wire brush. All power cables should enter the switch next to transfer mechanism terminals. If ALUMINUM con- ductors are used, apply corrosion inhibitor to con- ductors. Tighten terminal lugs to the torque values as noted on the decal located on the inside of the door. After tightening terminal lugs, carefully wipe away any excess corrosion inhibitor.

All power cables should enter the switch next to the transfer mechanism terminals.

Use a torque wrench to tighten the conductors, being sure not to over tighten, or damage to the switch base could occur. If not tightened enough, a loose connection would result, caus- ing excess heat which could damage the switch base.
