Installation & User Guide

3. Electrical wiring

3.1 Flow pulse cable connection

It is recommended to use copper wire cable with the cross-section 0.3 ... 0.5 mm2. By means of tweezers
remove a protective knoll from 1 sealant hole of electronic unit. Run the cable through the hole and
anchor with clamp. Use two wire connection methods –connect to the terminals 18 and 19 as shown in
the picture.
Terminal Nr. Description
18 Volume pulse output (+)
19 Ground (-)

3.2 External power supply module (if used)

Terminal Nr. Description
54 Mains supply 24 V AC/DC (bipolar)
55 Mains supply 24 V AC/DC (bipolar)

Pulse output
Measured flow rate is converted into the volume pulses which are transferred through pulse output
terminal. Pulse output class of flow output device: OD according to EN1434-2 + AC:2007. Maximum flow
cable length from electronic box to energy calculator or pulse reading device is up to 100m.
Values of output pulses:
Nominal (permanent) flow rate qp
0.6, 1.5, 2.5, 3.5 and 6.0
10, 15, 25, 40 and 60
