Connecting The External Pulse Inputs; Disconnecting The Serial Interface Cable - Honeywell CNI4 Operating And Installation Manual

7 Getting Started

7.4 Connecting the external pulse inputs

(Applicable for wall-mounted units only)
It is possible to connect a maximum of two external pulse inputs at TB2 (Terminal Block 2) of the Pulse
Accumulator.
A 3.5 VDC wetting voltage is provided by each Pulse Accumulator input channel. If the pulse channel is to
be wired to an active device, i.e. transistor-type output, then be sure to observe polarity.
To connect the external pulse inputs
1. Remove the housing on the cable gland and route the pulse input(s) cable through it.
2. Unplug the male 4-pin terminal block connector.
3. Connect the external input pulse wires of the cable into the appropriate slot on the 4-pin terminal
block connector.
4. Reconnect the 4-pin terminal block connector.
