Operating instructions

CAUTION!

Warning of unnoticed diaphragm rupture

Only above approximately 2 bar system back pressure is a

signal generated upon a diaphragm rupture.

– Only rely on the diaphragm rupture sensor at back pres‐

sures greater than 2 bar.

7.2 Installation, electrical

WARNING!

Danger of electric shock

Unprofessional installation may lead to electric shocks.

– All cable cores cut to length must be provided with cable

end sleeves.

– The Installation, electrical of the device may only be

undertaken by technically trained personnel.

CAUTION!

Warning about personal and material damage

Also observe the "General Operating Instructions for ProMi‐

nent

Motor-Driven Metering Pumps and Hydraulic Accesso‐

ries"!

7.2.1 Control connectors

CAUTION!

Incoming signals can remain without effect

If the universal control wire, the external/pacing cable or the

level monitoring cable is shortened below 1.20 m, the pump

does not detect that it is connected. Consequently a warning

message (for example) can be suppressed.

– Do not shorten this cable below 1.20 m.

Connect the plugs of the level switch, diaphragm rupture sensor and

dosing monitor to the corresponding sockets on the front side of the con‐

trol. In case of uncertainty - see chapter "Overview of equipment and con‐

trol elements"
