3.4 | Relay output wiring
Each output provides a NO and a NC output. The NO, C
(COMMON), and NC terminals are available in each terminal
or connection output position. The silkscreen on the edge
of the circuit board shows the function of each terminal and
the relay output number.
The middle terminal of each output position is the
COMMON and is labeled C. When the output is inactive,
the NC (Normally Closed) terminal has continuity with the
C terminal. When the output is active (energized), the NO
(Normally Opened) has continuity with the C terminal.
NOTICE!
Do not exceed relay contact ratings of 1.0 A, 24
VDC, resistive load.
4 | LED descriptions
The module includes one heartbeat LED to indicate that
the module has power and to indicate the module's current
state. Refer to the following table.
Flash Pattern Function
Flashes once
Normal operation state.
every 1 second
3 quick flashes
Communication error state: Indicates an
every 1 second
SDI2 communication error.
ON Steady
LED trouble state: Not powered (for
OFF Steady only), or some other trouble
condition.
OFF Steady
5 | Show the firmware version
With a tamper switch:
1.
Open the enclosure door.
2.
Push and release the switch
Without a tamper switch:
1.
Quickly short the tamper pins.
2.
Refer to the illustration below.
When the tamper switch is on, the heartbeat LED stays OFF
for 3 second before showing the firmware version. The LED
flashes the major, minor, and micro digits of the firmware
version, with a 1 second pause after each digit.
For example, the version 1.4.3 shows as LED flashes:
[3 second pause] *___****___*** [3 second pause, then
normal operation].
