Function
Signal relay 1 (LIVE or PELV)
Signal relay 2 (PELV only)
Digital input/output, configurable.
Open collector: Maximum 24 V resistive or inductive.
External sensor.
Pressure sensor: Pressure signal, 0.5 to 3.5 V. Connect the
white wire to this terminal.
Digital input, configurable.
Digital input 1 is factory-set to be start or stop input where an
open circuit results in stop. A jumper has been factory-fitted
between terminals 2 and 6. Remove the jumper if digital input 1
is to be used as external start or stop or any other external
function.
