CONTROL PANEL COMPONENTS (PARTIAL) AND CONTROL PANEL
TERMINAL STRIP TS2
NOTE:
DOTTED WIRES BY CUSTOMER
NOTE A:
To normally open initiating contacts I of automatic transfer switch.
NOTE B:
The yellow wire from voltage level rheostat (R2)to terminal 7 on the regulator terminal strip is disconnected at terminal 7.
NOTE C: Some generator sets without an Annunciator panel (remote) or a Prealarm module are not equipped with B + connection
from TS1-2 to TS1-30 to TS1-29 and TS1-15.
NOTE D: Some generator sets are grounded at the line from the current transformer's neutral. Some are grounded through a jumper
between TS1-20 and a terminal strip support screw.
NOTE E:
To normally open auxiliary contact on emergency side of transfer switch, if the generator set is equipped with an
Annunciator panel (remote). Used to give generating indication.
NOTE F: Red jumper between TS2-4A and TS2-4 is not used with cycle cranking module.
NOTE G: Do not operate the alternator without a battery connected in the circuit. Do not polarize alternator. Do not charge a
common battery with the alternator and a. DC generator at the same time.
NOTE H: To optional remote low lubrication oil pressure indicator installed by the customer.
NOTE I:
To optional remote shutdown indicator installed by the customer.
NOTE J:
On some generator sets, underspeed switch (USS) is connected to the common terminal on oil pressure switch (OPS).
Connect the wire to the normally open terminal on oil pressure switch (OPS) to help prevent low oil pressure shutdown when
engine oil pressure does not increase as fast as engine speed during engine starting.
NOTE K:
If terminal 1 is connected to terminal 2 speed switch will shutdown engine at 3/4 overspeed set point. Speed switches with a
verify button do not have terminal 1. Push the verify button to shutdown the engine at 3/4 overspeed set point.
NOTE L:
Some frequency meters are connected phase (TS2-FM to TS3-22 to stator T7) to neutral (TS2-TO to TS3-26 to stator TO).
Others are connected phase (TS2-FM to TS3-22 to stator T7) to ground (control panel chassis). When the frequency meter
is connected phase to ground, terminal TS2-TO has a mark 93 and is not connected to TS3-26.
NOTE M: CTS is a replacement for USS. CTS, crank terminate switch, gives a better description of the actual purpose of the switch.
