Contacts
Inputs
The analog inputs can be used as digital or analog
contacts. For analog use, resistance values can be
specified to check for cable breaks and short-circuits.
Relay outputs
The relay outputs offer the following functions:
• The outputs can operate with potential free contacts
for external power supply (dry mode).
• The outputs can operate using the internal voltage of
power supply (wet mode).
• Only ohm resistive loads can be connected to the
relay.
• Inductive loads must be bypassed via recovery
diodes. These diodes (IN4004) are enclosed.
General instructions
• All access equipment should be mounted within a
"secured area".
• Detailed connection conditions are specified in the
operating manual!
• After purchase, primary AC power must be carried
out by a licensed electrician.
