6. ACCEPTANCE TESTS

8.Remove the current from terminals A1-A2. Remove voltage from digital input CC1.

9.Repeat these steps with minimum and maximum voltages depending on the range of the relay.

Test voltages and typical burdens are listed below:

Model "G" (48/125 VDC)

		DC Battery (mA)
	Voltage (Vdc)	Without Expansion Board	With expansion Board
	38	340	440
	125	250	320
	150	225	300
Model "H" (110/250 VDC)

	DC Battery (mA)
Voltage (Vdc)	Without Expansion Board	With expansion Board
88	300	370
110	250	320
300	150	220

6.7. COMMUNICATIONS

The object of this test is to check the communication ports of the relay (PORT1, PORT2 and PORT3). To do this it is necessary to use a computer and the communications software GE_LOCAL. Figure 7 shows the series cable and connection accessories necessary to establish the connection between the PC and the relay. Figure 8 shows the cable and connectors necessary for remote connection (by MODEM) through PORT3.

The PC communication parameters necessary to match the relay default setting parameters are:

Relay number:	1
Remote port speed:	19200
Local port speed:	19200
Remote stop bit:	1
Local stop bit:	1

By using GE_Local communications software establish the connection and check that the relay communicates through the three communication ports. Repeat this test with different baud rates and different power supply voltages.
