Solution
Check power supply connections to the
device. Check Fuse if fitted.
Replace controller or modules if faulty.
Check supply voltage. Check for correct
DyNet voltages at each device. Isolate
and energize to determine if the fault is
external to the controller. Replace
controller or modules if faulty.
Check DyNet port wiring, verify button
panel is operating correctly. Check if
emergency state has been activated.
Check load wiring for short circuits.
Verify device loading with current tester
(remember to de-rate for specific loads
and install conditions).
Check total earth leakage.
Check wiring terminals are tight.
Perform a full power cycle to clear fault
condition.
Check that bus cable is connected to
drivers.
Inspect the driver to confirm the driver
type.
Check cable polarity if using 1-10V control.
Check wiring against the driver
manufacturer's diagram.
Check if the driver is DALI certified. Check
for correct DALI bus voltage: 12–21 VDC.
Disconnect third party equipment to
isolate the system and identify the cause.
