XLS Series Solid State Soft Starter 39 - 1250A
4.2.6 Programmable Relay
The XLS includes a programmable relay on TB2 which is located on
the main control board. The relay is rated for 240 VAC, 5 A and 1200
VA. The relay responds to either a fault condition or an up-to-speed
condition. For the relay to act as a fault relay, turn dip switch 1(SW1),
located on the main control board, “ON” and dip switch 2 “OFF” (Factory
Setting). For an up-to-speed contact turn dip switch 1 “OFF” and dip
switch 2 “ON”. Refer to Chapter 9 for dip switch location. In the up-to-
speed mode, the programmable relay can be used to control a bypass
contactor, or signal other systems that need to be brought online after
the motor has reached full speed.
4.2.7 Run Contacts
Auxiliary contacts are available on TB2. These contacts are rated 240
VAC, 5 A, 1200 VA and are for external use. Auxiliary contacts energize
(change state) when the start command is given and de-energize
(change back) when stop, or fault, condition occurs. In the decel mode,
the run contact can be modified to drop out at the stop command, or
to stay latched until the end of the decel command. Dip switch 5 is
“ON” and dip switch 6 is “OFF” for normal start/stop mode. To keep
the run contact latched until the end of decel, turn dip switch 6 “ON”
and dip switch 5 “OFF”. The decel mode must be enabled by turning
dip switch 4 “OFF”. Refer to Chapter 9 for the main control board
layout.
4.2.8 Emergency Shunt Trip Relay
The shunt trip relay at TB2 on the main control board will activate
when a shunt trip signal is received from the motor’s monitoring logic.
This relay is rated for 240 VAC, 5 A, 1200 V. This relay can be used in
an external shunt trip circuit. Check inrush rating on shunt trip breaker.
This relay is not programmable and only operates if current is flowing
when the XLS is in the off mode. Refer to Chapter 9 for the main
control board layout.
4.2.9 Fault Signal
An optical AC switch triac driver is used for fault indication. This signal
energizes with the fault LED. The optical output is rated for 240 VAC,
50 mA (maximum).
