Troubleshooting, alarm:
Observation indication
Cause/action
Check that the DIP switches are
correctly set
DIP switch “ON” to the left.
No LED illuminates
Check that 230 VAC ±10% is on the mains terminal.
If the mains voltage is correct, replace the control unit.
Rotation alarm
• Belt broken
• Belt dislodged
• Rotor stuck
• Magnet sensor or magnet not intact
Overvoltage
The feed voltage is above 265 V. Ensure correct voltage to the unit.
Undervoltage
The feed voltage is below 190 V. Ensure correct voltage to the unit.
Over/under temperature
The temperature in the control unit is above +85°C or below -30°C.
Short circuit
• Short circuit between phases in cable or motor
• Earth fault between phase-earth in cable or motor
• Interrupt in one phase in cable or motor (measure motor resistance,
should be the same on all windings)
Internal fault
Internal control fault has occurred.
The motor is difficult to start-up,
weak
Check that the phase order is correct according to the wiring diagram.
GENERAL
This section describes functions and settings for time switch programs and calendars.
When no object with higher priority (for example Manual mode <> Auto) is enabled,
the unit can be switched off or the stage changed (stage1...3) via the time switch pro-
gram. Up to six switching times can be specified for each day of the week.
Calendar stop overrides calendar exception, which in turn overrides the normal time
switch program (only in operating mode). Up to 10 periods or exception days can be
specified for each calendar.
Time switch program.funct. = Stage+Temp: Setpoints for both fan stage and tempera-
ture (comfort/economy) are controlled by the time switch program.
