 Measuring the Input Transducers

Apply direct current on the Input Transducer and check that the measurements taken from

Communications or on the Measurements Screen of the display coincide with those of the

following table whenever the constant of the Transducer is in “1”.

10.7 Communication Test

To carry out the Communication Test, it is necessary to supply the equipment with its rated

voltage value and the In Service LED should then be switched on. Test will be performed

through Local Communications Port, allocated on Front Panel. This port has the fixed settings

that follow:

Baud Rate 4800 Bauds

Stop Bits 1

Parity 1 (even parity)

Connect to the terminal unit through the Local Communications Port using a DB9 (9-pin) serial

connection wire. Synchronize time using the ZiverCom

software program. Disconnect the

communications wire and disconnect the terminal unit Power Supply and wait for two minutes.

Afterwards, connect the Power Supply and connect to the terminal unit through the Remote

Communications Port. Activate the “cyclical” mode in the ZiverCom

software program and

verify that time actualizes properly.
