Technical Description
4.3 Power Supply LED Signals
LED signal
With each the specified disturbances, and without power, the contact of the malfunction signal output opens.
Wireless Proximity Switches / Issue: 09.2004
Explanation
All LEDs off:
Power Supply is switched off (no mains supply!)
The left LED blinks green:
After switching on, the power supply is in the
Start-mode (for approx. 20 - 30 sec.).
The left LED is green:
Power Supply is in normal operation mode.
The LED in the middle blinks red:
Disturbance due to one of the following:
• Over-temperature
• Instability of control
• Difference in internal current measurements
These errors turn off the power supply
The LED in the middle is red:
Disturbance due to one of the following:
• Cut cable in the primary loop(s)
• Short-circuit in the primary loop(s)
• Set current can not be achieved
• High coupling between two loops/devices:
Device switches off
The right red LED blinks:
Disturbance due to one of the following
• Wrong setting of DIL-switch S2
(Master/Slave; Phase)
The right LED is red:
Sync-error due to one of the following:
• Cable cut, short circuit, wrong polarity, mistaken
in-/output connection via sync-cable
• All devices connected via sync-wire are slaves
• Several Masters present
Recommended Action
• Switch Device off and on again.
If the error occurs again:
-> Exchange Device
• Check primary loops regarding cut
cables or short-circuits, eliminate
fault.
• Check geometry / symmetry of
primary loops according to the
installation guidelines
• Check and correct setting of
DIL-switch S2
• Check the synchronisation-cables
and correct possible errors
• Check the DIL-switch S2 of all
devices regarding correct
Master/Slave setting with respect
to the wiring.
