VARIO2 POE Troubleshoot
Step 1 : Check Power to the Unit
Check LHS indicator is green to show the unit is receiving power.
If powering from PoE, ensure Power Sourcing Equipment (PSE) is suitably
rated for the VARIO2 POE unit – see page 6 for required ratings – and
for all 8 size units check correct PoE Detection Resistance has been
selected – see page 7.
If powering from low voltage 24V DC, check voltage applied and that
power supply is suitably rated for the VARIO2 POE unit – see page 7 for
required ratings.
•
Check polarity of illuminator connection red=+ve, black=-ve
•
Ensure power is 24V DC
If longer cables used, ensure sufficient voltage is provided to allow for
drops across the cable
Step 2 : Check Photocell and Telemetry Input
Check photocell is working. Cover photocell fully, light should turn on.
(Note : It is sometimes difficult to see Infra-Red illuminators working in
high brightness conditions).
•
If Premium variant - Ensure telemetry wires are shorted out or valid
telemetry input (zero volt or TTL) is applied and correctly wired
