operation
The switch can be remotely reset after being tripped by applying the correct
voltage across the reset terminal as shown below in
Figure 5
.
There is no positive/negative polarity needed for the wiring. While
the power is applied to the remote reset terminals, the switch
cannot be tripped.
24 VDC Switch
—A 24VDC power supply is needed to remotely reset the
switch by energizing a solenoid. The 24VDC power source must be capable
of supplying at least 2A of current. Upon power up, the unit will need the 2A
to energize the remote reset coil. Depending on ambient temperature, this will
decrease to approximately 0.4A after 5-10 seconds. After that time, the coil
can be energized indefinitely.
To protect the remote reset solenoid from overheating, the unit has a built in
thermistor that will limit the coil current after a certain amount of time. This
time is dependent on ambient temperature and if the reset coil was recently
energized. Since the coil needs the peak current only for a short period of
time, the thermistor lowers the current but it is still strong enough to hold the
switch in reset mode.
The switch will start feeling warm to the touch if the remote reset coil is
left energized for more than a few minutes.
120 VAC Switch
—A 120VAC, 60Hz power supply is needed to remotely reset
the switch by energizing a solenoid. Upon applying 120VAC to the solenoid,
the unit will need 184mA to energize the remote reset coil. At standard ambi-
ent temperature, the solenoid has a 25% “on” 75% “off” cycle.
Maximum allowed On Time (remote reset energized) versus minimum
Off Time (remote reset de-energized).

If using the solenoid for a power on delay, do not exceed the “on” times
listed. If the “on” time exceeds 4 minutes and/or the “off” time is shortened
before energizing the solenoid again, the solenoid will be permanently
damaged.
