Effective June 2000
Optional Feature 12G –
Normal Available Pilot light.
A white 30mm indication light indicates that
the normal source is available.
Optional Feature 12H –
Emergency Available Pilot light.
A white 30mm indication light indicates that
the emergency source is available.
Optional Feature 14 – Auxiliary Relays
120VAC instant relays labeled NRA (Normal
Source) and ERA (Emergency Source)
provide the user with up to six (6) form C
contacts for switch status indication. The
relays are energized when power is
available and the switch is currently
connected to the source. The contacts are
wired to terminal blocks beginning with
number 501. See the schematic shipped
with the unit for more detail.
Optional Feature 15 – Auxiliary Contacts
Auxiliary switches mounted inside the
breakers follow the breaker position,
regardless of power availability. The form C
contacts are wired to terminal blocks
beginning with number 401. See the
schematic shipped with the unit for more
detail.
Optional Feature 16 - Integral
Overcurrent Protection
Provides ovecurrent protection integral to
the power switching device. The use of this
option can, in many cases, eliminate the
need for separate upstream,
overcurrent/short-circuit protection. For
safety purposes, this option includes a lock-
out function that prevents further automatic
transfer operation until the appropriate
source is manually reset. The MP1
controller will also read ***LOCKOUT*** on
the display. See the front of the switch
mechanism for instructions. (Note: Four
pole transfer switches include overcurrent
protection only on the three power poles)
Optional Feature 18 – Metering and
Communications
Analog meters or Cutler-Hammer IQ
metering devices can be installed to provide
various metering functions. Refer to the
appropriate instruction manuals that ship
with the transfer switch for additional
information.
Optional Feature 24 – Battery Charger
A 5A trickle charger with DC output of 12V
or 24V is mounted either inside the switch
enclosure or supplied loose and externally
mounted. Refer to the specific instruction
manuals that ship with the transfer switch for
additional information.
Optional Feature 30 – Cranking Limiter
An externally mounted timing relay,
adjustable from 0-120 sec. The relay will
interrupt the engine start circuit if voltage
does not appear on the emergency source
within the pre-selected time. When setting
the time delay, make certain the TDES and
the warm-up time of the genset is taken into
account.
