Time Delays
2C Provides an extended time delay on engine starting.
The standard feature one time delay is adjustable
from zero to six seconds. Accessory 2C allows this
time delay to be adjustable from zero to sixty minutes
in one second intervals factory set at five minutes.
1G Similar to accessory 2C except using 24 volt DC
external input signal. 7000 SerieS controller remains
active when both power sources are de-energized*
1GB Same as accessory 1G except using 120 volt AC
external input*
* add suffix 1 to include external power to power manager or
power meter when applicable
Manual Controls for Automatic
Transfer Switches
6C Reset switch for manual retransfer to normal with
automatic retransfer in the event of emergency
source failure.
6D Selector switch for automatic/manual retransfer to
normal. Automatic bypass if emergency fails.
Indicators
14A/14B Additional auxiliary contact sets to indicate switch
position. Two sets are standard. Specify total num-
ber of sets if more are required.
18B Two-pole, double-throw contacts operate when
emergency source voltage is present at transfer
switch terminals.
18G Two-pole, double-throw contacts operate when normal
source voltage is present at transfer switch terminals.
99 “Push-to-Test” feature on all pilot light indicators.
Customer Control Circuits
30A Load-shedding circuit initiated by opening of a
customer-supplied contact.
30B* Load-shedding circuit initiated by removal of
customer-supplied control voltage. *(Specify voltage).
31Z Selective load disconnect control contacts (two
provided) which operate with time delay prior to and/
or after load transfer and retransfer.
43R Terminal block for all customer control connections
on 30-150 amp only (standard on all other sizes).
Neutral Conductor Options
• Solid neutral, with fully-rated terminals. (AL-CU) UL Listed.
• Conventional neutral switching pole.
• Overlapping neutral transfer contacts. Allows for proper
ground-fault sensing and avoids generator voltage
transients during transfer.
Note: Specify neutral option in catalog number, see page 22 for instructions.
Extension Harness
37B Six foot (6’) extension harness to increase distance between
transfer switch and control panel on open-type units.
Communications
72E 5150 Ethernet Connectivity Module offers
communication to transfer switch and metering
with embedded webpages.
72SW An Industrial Ethernet Switch mounted in the
enclosure used in conjunction with 5150
Connectivity Module (acc. 72E) metering device.
Includes 2 available Ethernet ports and 2
multimode ST Fiber connectors.
Surge Protection
