Diagnosis
Check for obstructions
Check system settings item
in the menu to check the
device type setting for the
input
INP1/2/3/4 inputs are
compatible with dry-contact
type devices. Ensure the
device being used is a dry-
contact type device.
Check wiring for short or
open circuit
Ensure wires are wired into
correct terminals

Resolution
If obstructions are
present, remove the
obstruction
Ensure the device type
matches the device that
is actually installed
If the device is
incompatible, replace
with one that is, or move
the device to another
input which is compatible
with the device
Correct wiring faults
If a known-good device
works, replace the faulty
device
If the main board still
detects an obstruction
with no device
connected, power cycle
the operator.
If the problem persists,
reset to factory defaults
and configure again.
If problem still persists,
replace the powerhead
main board.
