This device conforms to European Union Directive 2004/108/CE and 2006/95/CE as
amended with reference to generic standards:
EN 61000-6-2 (immunity in industrial environment)
EN 61000-6-4 (emission in industrial environment)

Alarm Outputs
The alarms are only available only on models rated at 50 Amps and greater.
There are two types of alarm outputs:
1. Solid State Switch – Controls a connected device for an alarm event, such as a
horn or light.
a. Requires external 24VAC/DC power supply
b. Ratings: Imax = 150 mA
Vmax = 30 VAC/DC
Z close < 15 ȍ(impedance)
Z open > 1 Mȍ(impedance)
2. Digital Logic – PNP output signal for logic gated devices, such as PLCs
a.
Requires external 24VDC (6-32 VDC) power supply
b. Ratings: Imax = 150 mA
Vmax = 30 VAC/DC
Alarm Behavior
The functionality of the alarm switching varies depending on the type of gating signal
For Models with 24 VDC Input Control Signal
The alarm output function actuates (opens or closes) the isolated solid state output
switch (or digital output signal) when it detects any of the following fault conditions:
The control signal is active, but:
• There is no current on the load (zero current or interrupted load)
• There is no line voltage power supply
• The internal temperature limit of the SSR has been exceeded
Latching Alarm Function
On the VDC gated CS1 controllers, the alarm state remains latched if the Control Signal
is switched off. The Alarm Output will reset (unlatch) once the current load is restored
or when the CS1 24 VDC power supply is cycled.
For Models with 20 - 260 VAC/DC Input Control Signal
The alarm output function closes the isolated solid state output switch when it de-
tects any of the following fault conditions:
The control signal is active, but:
• There is no current on the load (zero current or interrupted load)
• There is no line voltage power supply
• The internal temperature limit of the SSR has been exceeded
Latching Note:
On the VAC gated CS1 controllers, in the absence of the control signal, the alarm
output is always open. The alarm memory latch function is not possible as with the
CS1 with VDC control signal.
Integrated Thermal Protection
The SSR temperature is constantly monitored. If the maximum temperature limit
(230°F/110°C) is exceeded, current to the load is interrupted and the YELLOW over-
temperature condition LED illuminates.
