Important: The common power connection (terminal 93) must be
connected to Earth. ABB Cylon recommend that this is done at
the 24 V AC transformer.

Universal Inputs
1 ... 12
When input is configured as Digital:
• LED Off: open circuit or logic 'off'
• LED On: logic 'on'
When input is configured as Resistor/thermistor:
• LED Off: valid resistance connected (Note: 0 Ω is counted as
valid)
• LED Slow blink: resistor/thermistor not connected
When input is configured as Analog:
• LED intensity is modulated by the analog signal
When the LED is blinking:
• Fast blink indicates error condition
• Two short flashes followed by a value* indicates the input is in
an override state (overridden by
*Note: The LED intensity illustrates the value measured at the input
terminals. The flash indicates that this value has been overridden.
25 ... 38 UniPuts™ + Relay
When a Uniput channel is configured as an input, the LED signals are
identical to Universal Inputs above. When configured as an output the
following apply:
When output is configured as Digital:
• LED Off: open circuit or logic 'off'
• LED On: logic 'on'
When output is configured as Analog:
• LED intensity is modulated by the analog signal
