If necessary, set parameters
Relay #1 Mode
to
Relay #4 Mode
and
SysOK
Relay
Mode
to their initial mode.
4.2.7
Verifying the Standard TDM Signal (If Used)
This procedure requires a Hydran 201C
i
-C Controller.
4.2.8
Verifying the Analog Input(s) (If Used)
The procedure described below should be performed for each optional 4
–
20 mA
analog output interface installed on the right side of the electronic card cage. Each
analog output terminal block has four terminals.
1.
Configure the analog inputs before verifying them. See Section 4.4.7.
2.
Connect a 4
–
20 mA calibrator-simulator (for example: Model CL-303-2 from
Omega) to terminals 2 (
-
) and 3 (
+
) of the analog input terminal block to verify.
For technical details on the terminal block, see Section D-2.

An. Input Setup
and select the analog input
interface to verify. In the screen that is now displayed, proceed as follows:
•
Set the calibrator to 4 mA.
–
IO State
should display 0.0 ± 0.1 %.
–
The line below
IO State
should display the minimum reading value
(defined during the configuration).
•
Set the calibrator to 20 mA.
–
IO State
should display 100.0 ± 0.1 %.
–
The line below
IO State
should display the maximum reading value
(defined during the configuration).
•
Set the calibrator to 12 mA.
–
IO State
should display 50.0 ± 0.1 %.
–
The line below
IO State
should display the middle reading value.
4.
Disconnect the digital multimeter.
Note: If the input reading does not correspond to one of the above values,
calibrate this analog input.
4.2.9
Verifying the Analog Output(s) (If Used)
The procedure described below should be performed for each optional 4
–
20 mA
analog output interface installed on the right side of the electronic card cage. Each
analog output terminal block has four terminals.
1.
Configure the analog outputs before verifying them. See Section 4.4.8.
