Sterling M2B+ - 4-5 Selecting a Local Probe; Using a Remote Input Probe for Monitoring

M2B+ Controller
4-5 Selecting a Local Probe
The controller has two standard temperature probe inputs for delivery (to process) and return
(from process). The probes are typically set up at the factory, but they can be re-configured in
the field. To set up this feature you must have access to the Secure Menu. See Section 2-6 on
page 16 to review accessing the Secure Menu.
Use the following procedure to select a local probe:
1. Press the Index button three times to access the Secure menu.
2. Press the Enter button.
3. Press the Index button until the display reads “Sensor type = RTDIK.”
4. Use the Up and Down buttons to select the sensor type.
5. Press the Enter button to accept the value.
When changing the sensors from RTDs to thermocouples, you must also change the
jumpers JMP1 and JMP3 to pins 2 and 3.
6. Press the Alarm Silence button to return to Running mode.
Using a Remote Input Probe for Monitoring
The Remote Probe Input can be used for two different functions: To control or monitor the
temperature of a process outside of the temperature control loop. To set up this feature you
must have access to the Secure Menu. See Section 2-6 on page 16 to review accessing the
Secure Menu.
This option can be purchased with or without the manufacturer supplying the actual
temperature-sensing device. If the manufacturer supplies the probe, the controller is
preconfigured, and the user needs to set up the controller as local or remote input.
Use the following procedure to monitor the process from the remote probe:
1. Press the Index button three times to access the Secure menu.
2. Press the Enter button.
3. Press the Index button until the display reads “Sensor Monitor.”
4. Press the Enter button.
5. Use the Up and Down buttons to select the type of input desired. Select “MON” for
monitor. The LCD display will change to have MT display the monitored
temperature from the probe.
If the display reads “999,” the probe is not plugged into the back of the controller at
pins 3 and 4 of the 8-pin connector.
6. Press the Enter button to save the sensor monitor parameter.
7. Press the Index button until the display reads “Mold Sensor Type.”
8. Press the Enter button.
9. Use the Up and Down buttons to select the type of mold sensor (Type J, K, or T
thermocouples or 100 or 1000 ohm RTD).
10. Press the Enter button to save the mold sensor type.
11. Press the Alarm Silence button to return to Running mode.
