Special
conditions
For connection to a NAMUR amplifier, the digital output (terminals, 51/52, 41/42,
81/82) can be wired internally as a NAMUR contact by setting a jumper (for details see
Service manual). Open Collector or NAMUR configuration is carried out at the factory in
accordance with the order details. If no configuration was specified in the purchase order,
the digital output is configured as Open Collector.
