Maintenance / Repair

Power relay output
for alarm triggering:
Power relay output for
controlled variable output (M)
or limit value signalling (G):
When switching inductive loads, a corresponding protective circuit must be provided for the relay
contacts, e.g. RC circuits. Typical RC combinations for 230 V AC: Capacitor 0.1 µF / 630 V, resistor 100
Ohm / 1 W.
If consumers with an increased switch-on current (e.g. plug-in switched-mode power supply units) are
switched, a switch-on current limitation must be provided.
WARNING
If line voltage is supplied to one of the terminals XR1-XR3 or XP, no safety extra-low
voltage (SELV) may be connected to any of the other terminals!

Safety information
WARNING
• The device or system must be disconnected from the power supply before starting any
maintenance work. The DULCOMETER
The power supply must therefore be interrupted by means of an external master switch
or by a main fuse. General safety regulations are applicable at all times!
Even when the voltage supply is switched off, mains power may still be applied at
terminals XR 1-3!
• Fuses must only be replaced by corresponding original fuses!
• Only use fuses of the specified manufacturer!
Only use 5 x 20 mm miniature fuses!
