Short Circuit
Description
Measurement
Possible Cause
Action Required
Resistance
Voltage
Zone 1 Short
Circuit
< 50
Ω
0 V DC
The input or output is measuring the
indicated resistance range, across the
negative and positive terminals of the
circuit.
Check cabling and routes for physical
or water damage.
Zone 2 Short
Circuit
Ensure cable is routed minimum
500 mm from high voltage cables.
Zone 3 Short
Circuit
When a short is measured by the
panel, the circuit will automatically
isolate, and the fault will latch. Voltage
cannot be measured during this
protection mode.
Ensure correct value EOL is in place.
Zone 4 Short
Circuit
Check field device termination and
polarity.
Zone 5 Short
Circuit
To confirm the panels indications, the
resistance should be measured with
the circuit cabling removed from the
Main PCB (disconnect terminal block).
If short persist after completing above
checks, break zone cabling at the field
devices, in smaller sections, to reduce
the search area.
Zone 6 Short
Circuit
Zone 7 Short
Circuit
Once the resistance measurement
confirms you have a short on the field
cabling proceed to "Action Required".
If the problem persists, please contact
your supplier.
Zone 8 Short
Circuit
Input 1 Short
Circuit
If the cable is clear, insert an EOL
across the affected input or outputs
terminals at the panel to confirm that
the product is not faulty.
Input 2 Short
Circuit
Sounder 1 Short
Circuit
If the problem persists, please contact
your supplier.
Sounder 2 Short
Circuit
