Functions And Features; Applications - ProMinent DULCOMETER PH-501 Assembly And Operating Instructions Manual

High-pressure units (250 bar, 400 bar) are supplied with an integrated damping
device to comply with the regulations for UL approval and to avoid any risk of
injury in case of bursting when bursting pressure is exceeded.
Any manipulation of the damping device is not permissible.
When the damping device is removed, there is no damping function
any more. ATTENTION: risk of injury!
For units with cULus approval this approval becomes invalid when the
damping device is removed.
For the scope of validity cULus:
The Sensor shall be connected only by using any R/C (CYJV2) cord, having suit-
able ratings.
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).
