5.3 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, 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.

You can use the MasterLink Software (R510.1 or higher) to configure the Pulse Accumulator and the

Cloud Link 4G Modem as two independent sites, using the USB-to-serial cable (40-6147-kit).

One end of the cable has a USB connector and the other end includes a male and female connector. The

male (black) connector connects to the Cloud Link 4G Modem, and the female (green) connector connects

to the Pulse Accumulator.
