Fault tracing
114
OVER TEMP FAULT
Supply unit has exceeded temperature
fault limit.
Check ambient temperature. Check cooling air flows
freely. Check fan operation. Check inlet and outlet air
filters. Check heatsink for dust pick-up.
DC FUSE
DC fuse blown.
Change DC fuse.
EXTERNAL FAULT
Digital input indicates external fault.
Fix external fault. Check status of digital input.
EM STOP /
OTHER FAULT
Blinking: Internal fault detected by DSU
control program, e.g:
- DSU charging failed or exceeded
allowed duration (5 s.).
- Module switch-disconnectors do not
open/close, or DSSB board receives
false switch-disconnector status signal
(auxiliary contact).
- Emergency stop circuit is open, or not
connected correctly.
- Loose connectors -X4 or -X8 on
DSSB board.
- 4A fuse(s) blown on DSSB board.
Check fuses on circuit boards.
Reset DSU and restart.
Check operation of switch-disconnectors (optional
equipment). Check status signal. Check/tighten
signal connections. Replace module (or
switchdisconnector.)
Release emergency stop button. Check connections
of the emergency stop circuit.
Check that connectors -X4 and -X8 are properly
fastened.
M/-24VDC from DSSB board connectors
-X4 and -X8. Change the 4A circuit board fuses F1
and F2 of DSSB board.
On:
- Module contactors do not open, or
DSSB board receives false contactor
status signal (auxiliary contact).
Check operation of contactors (optional). Check
status signal. Check/tighten signal connections.
Replace module (or contactor).
Reset DSU and restart.
EARTH FAULT
Supply load imbalance due to earth
fault leakage current in drive, motor
cable or motor.
Check motor, and motor cable. Ensure there are no
power factor correction capacitors or surge
absorbers connected to the system. If all of the
above are OK, raise earth fault trip level; see the
ACA631/633 User’s Manual for Cabinet-installed
Diode Supply Unit
(code: 64735501 [English]).
OVER TEMP WARN
Supply unit has exceeded temperature
warning limit.
See
OVER TEMP FAULT
above.
READY
Blinking: Supply module contactor is off
or module is charging intermediate
circuit. Input terminals are live and
module switch-disconnectors are
switched on. However, unit cannot be
loaded yet.
Contactors off: Close contactors.
Contactors on: Wait until supply unit has charged
intermediate circuit (i.e LED illuminates steadily) and
start to load the unit.
On: DSU is in operation and can be
loaded; Input terminals are live, module
switch-disconnectors and contactors
are on, intermediate circuit capacitors
have been charged.
Load/control DSU.
