1 Safety instructions
Read the product description before installing the unit. Ensure that the product•
is suitable for your application without any restrictions.
Non-adherence to the operating instructions or technical data can lead to•
personal injury and/or damage to property.
Inallapplicationscheckcomplianceoftheproductmaterials(→6Technical•
data) with the media to be measured.
For units with cULus approval and the scope of validity cULus:
Thedeviceshallbesuppliedfromanisolatingtransformerhavingasecondary
Listed fuse rated either
a) max 5 amps for voltages 0~20 Vrms (0~28.3 Vp) or
b) 100/Vp for voltages of 20~30 Vrms (28.3~42.4 Vp).
2 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•
reached.
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).

Avoid static and dynamic overpressure exceeding the given overload
pressure.
Even if the bursting pressure is exceeded only for a short time the unit can
be destroyed (danger of injuries)!
