•
Recommended screwdriver:
▪
0.6 × 3.5 mm
•
Tightening torque: 0.35 ... 0.4 Nm
Note: The output mode as well as standard or high-resolution
pulses can be parameterized via UltraAssist.
The pulse output module T45-PULSE enables the output of pulses on 2 con-
figurable channels.
On channel 1 (terminal 16, 17):
•
energy (CE)
•
volume (CV) or
•
tariff register 1 (C1)
pulses can be output.
On channel 2 (terminal 18, 19):
•
volume (CV)
•
tariff register 1 (C1) or
•
tariff register 2 (C2)
pulses can be output.
The pulse duration is identical on both channels.
