Verifying The Rs-232 Communications (If Used); Conclusion - GE Hydran M2-X Instruction Manual

2. Set a digital multimeter to dc current (1 % accuracy and 0.01 mA resolution)
and connect it to terminals 2 (-) and 3 (+) of the analog output terminal block
to verify. For technical details on the terminal block, see Section D-3.
3. Access Setup > I/O Setup > An. Output Setup and select the analog output
interface to verify. In the screen that is now displayed, set the Mode
parameter as follows:
• Press Change, select 0% and press Enter.
– For 4–20 mA analog outputs, ensure that the output current is 4.00 ±
0.01 mA.
• Press Change, select 50% and press Enter.
– For 4–20 mA analog outputs, ensure the output current is 12.00 ± 0.02
mA
• Press Change, select 100% and press Enter.
– For 4–20 mA analog outputs, ensure that the output current is 20.00 ±
0.02 mA
4. Set the Mode parameter back to Normal.
5. Check the 4–20 mA supply voltage.
6. Disconnect the digital multimeter.
Note: If the output current does not correspond to one of the three above values,
calibrate this analog output.

4.2.10 Verifying the RS-232 Communications (If Used)

This verification procedure requires Perception software.
1. With the supplied RS-232 cable, connect the Hydran M2-X to a laptop
computer through their DB-9 connector.
2. Access Setup > Comm Setup > Identification.
3. Note the value of parameter Monitor ID and set it to 1.
4. Run the Perception software on the laptop computer.
5. In the Relays/Analog menu of Perception, force on and off the alarm relays to
test communications.
6. In the Relays/Analog menu set the state of the alarm relays to Normal upon
completion of the tests.
7. Disconnect the RS-232 link cable.
8. Access Setup > Comm Setup > Identification.
9. Set parameter Monitor ID to its initial value (noted during step 3).

4.2.11 Conclusion

The Hydran M2-X verification is now completed.
1. Power down the Hydran M2-X.
2. Disconnect the power supply cable from the Hydran M2-X.
