6. ACCEPTANCE TESTS
8.Remove the current from terminals
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.
