3 Function and features
The pressure monitor detects the system pressure and generates 1 output signal.
• In case of increasing pressure the output closes when the Set1 value is rea-
ched.
• In case of decreasing pressure the output opens when the value „Set1 minus
hysteresis“ is reached.
The hysteresis is fixed (2% of value of measuring range).
