PROGRAMMING THE ANALYZER

3. Select Temperature

a. Press the Select key to toggle between enable

and disable. If the box is checked, temperature
has been selected.

b. Scroll to Units and select it. Choose the desired

units for temperature.

c. Scroll to Resolution. Press Select repeatedly to

change the resolution. The setting will be stored
as soon as you press any key to leave.

d. Scroll to Sentinel and press Select. Use the

arrow keys to change the setting.

5.5 CONFIGURING OUTPUTS

Outputs refer to the analog current loops and the alarm
relays.

Configure the probes before configuring the

outputs.

5.5.1 Current Loops

There are six settings to make:

•

Enable/Disable: Choose to enable or disable the
output loop.

•

Parameter: Assign a probe and parameter to the
output.

•

4 mA Value: Enter the value to correspond with 4
mA.

•

20 mA Value: Enter the value to correspond with 20
mA.

•

4 mA Trim: Adjust the 4 mA value of the analyzer to
achieve a loop current of 4 mA.

•

20 mA Trim: Adjust the 20 mA value of the analyzer
to achieve a loop current of 20 mA.

1. Select Menu, then Settings, then Outputs, then

Current Loops.

2. Choose current loop 1 or current loop 2.

3. Scroll to Enable/disable and select it. Press the

Select key to toggle between enable and disable. If
the box is checked, the current loop has been
enabled.

4. Scroll to Parameter and select it. Scroll through the

list of probes and measurements. A is probe A, B is
probe B, and C is the analyzer.

5. Scroll to 4 mA value and select it. Use the arrow

keys to change the setting.

6. Scroll to 20 mA value and select it. Use the arrow

keys to change the setting.

7. Scroll to 4 mA Trim: Use the arrow keys to adjust the

loop current to 4 mA.

8. Scroll to 20mA Trim: Use the arrow keys to adjust

the loop current to 20 mA.

5.5.2 Alarm Relays

There are six settings to make.

•

Enable/Disable: Choose to enable or disable the relay.

•

Mode: Choose High Alarm or Low Alarm.

•

Parameter: Assign a probe and a parameter to the
relay.

•

Setpoint: See Figure 5-2.

•

Deadband: See Figure 5-2.

•

Test: Manually energize or de-energize a relay to
test it.

1. Select Menu, then Settings, then Outputs, then

Relays.

2. Choose Relay 1 or Relay 2. For each relay there is

a high voltage and low voltage relay. Configuring the
relay configures both the high voltage and low volt-
age relay.

3. Scroll to Enable/disable and select it. Press the

Select key to toggle between enable and disable. If
the box is checked, the relay has been enabled.
