• All two-hand buttons must use test pulses. These pulses should be
entered in the configurator (DB 002) accordingly.
• Ensure the selector switch contact for input parameter Off has a test
pulse output and enter this output in the configurator (DB 002)
accordingly
• If the block is to be used to monitor a foot switch, the inputs of the N/O

or T1.4 and T2.4 respectively.
• In accordance with EN 574 section 3.5, 02/97, monitoring of the
synchronisation time between the two buttons is set at < 0.5 s.
