22.214.171.124.3 When the ENGINE CONTROL switch is placed in the OFF position, all power is removed from the governor
control circuit and the engine will stop.
126.96.36.199.4 The EMERGENCY STOP switch will remove power from the governor control circuit by de-energizing
circuitry in the DCS. This will cause the engine to shut down. The EMERGENCY STOP switch will not be
used as an alternative for routine shutdown procedures. When the generator set is stopped using the
EMERGENCY STOP switch, some circuits remain energized causing a drain on the batteries until the
ENGINE CONTROL switch is placed in the OFF position.
188.8.131.52.1 The generator set is capable of being operated in parallel with one other set of the same model number. This
capability is provided by the PARALLELING RECEPTACLE, paralleling cable, and the load sharing
184.108.40.206.2 The paralleling cable is used to interconnect the governor and automatic voltage regulator paralleling circuits
of the two sets. Voltage and frequency of the two generator sets are synchronized by the DCS load sharing
synchronizer. The permissive paralleling relay monitors the voltage phase relationship and prevents the AC
circuit interrupter from closing when the units are not properly synchronized.
LOCATION AND DESCRIPTION OF MAJOR COMPONENTS.
All locations (Figure 1-30) referenced herein are given facing the control box side (rear)
of the generator set.
COMMUNICATION RECEPTACLE (1). The COMMUNICATION RECEPTACLE is used to connect a
remote PC to the DCS control box to facilitate remote operation and monitoring of the generator set.
PARALLELING RECEPTACLE (2). The PARALLELING RECEPTACLE is used to connect the paralleling
cable between two generator sets of the same size and mode to operate in parallel.
CONVENIENCE RECEPTACLE (3). The CONVENIENCE RECEPTACLE is a 120VAC receptacle used to
operate small plug-in type equipment.
DCS Control Panel Assembly (4). The DCS control panel is located at the rear of the generator set and
contains the CIM, switches, and connectors used to control and monitor generator set operation.
Computer Interface Module (CIM) (5). The CIM is located in the DCS control panel assembly and contains
controls and indicators for operating the generator set.
Air Cleaner Assembly (6). The air cleaner assembly is located on the left side behind the AIR CLEANER
ACCESS door. It consists of a dry-type, disposable paper filter and canister. The air cleaner assembly
features a dust collector which traps large dust particles. The air cleaner assembly has a restriction indicator
which will pop up during operation when the air cleaner requires servicing.
AC Generator (7). The AC generator is a single bearing, drip-proof, synchronous, brushless, three phase, air-
cooled generator. The generator is coupled directly to the rear of the diesel engine.
