Frequently Asked Questions - ESM-9920 Emko

How to set the temperature setpoint?

Press the SET key to access the setpoint display. Use the arrow keys to change the value. Press SET again to confirm. If no action for 120 seconds, the device returns to the main screen.

How to configure an alarm?

Access the AL (Alarm) menu in the programming section. Use the parameters ALo1 (low limit), AUP1 (high limit), AHS1 (hysteresis), and Aon1/AoF1 (delays). The alarm type is selected with AAS1 (e.g., PH,R for high with latching).

What to do if the screen displays 'Sensor Error'?

Check the sensor connection (thermocouple or Pt100). Make sure it is properly connected and that the input type matches the sensor used. If the problem persists, replace the sensor.

How to clean the device housing?

Use a soft cloth slightly dampened with water or ethyl alcohol. Never use hydrocarbon-based solvents (petroleum, trichlorethylene) which could damage the plastic.

What is the panel mounting procedure?

Cut an opening of 92x92 mm (tolerance ±1 mm). Insert the sealing gasket, place the device from the front, then secure it using the two mounting brackets provided by tightening the screws.

How to start the PID auto-tuning?

Go to the Cont (Control) menu and set tune to SELF. Press ASET/OK to confirm. The device automatically calculates the PID parameters. Ensure the process temperature is below the setpoint by at least 5% of full scale for heating.

Which sensor types are compatible?

The device accepts thermocouples type J, K, R, S, T and Pt100 probes (2 or 3 wires). Refer to table 1 in the manual for the corresponding measuring ranges.

How to change the temperature unit between °C and °F?

In the ProS (Process) menu, set the parameter Un to °C or °F. The default value is °C. This change affects all displays.

What to do if the device does not turn on?

Check the power connection and the fuse (if present). Make sure the supply voltage matches the one indicated on the label (usually 100-240 V AC). If the device remains off, contact maintenance service.

How to lock access to parameters with a password?

In the Prot (Protection) menu, set PrPS to a code from 0 to 9999 (e.g., 1234). If the value is non-zero, the user must enter this password to access and modify parameters. To disable, set PrPS back to 0.

2-Check front panel gasket position
3-Insert the device through the cutout.If the mounting clamps are on the unit, put out them before inserting the unit to the panel.

4-Insert the unit in the panel cut-out from the front side.

5- Insert the mounting clamps to the holes that located top and bottom sides of device and screw up the fixing screws until the unit completely immobile within the panel.

Tune Operation

Starting the Tune operation

1-Enter to the programming section
2- Select SELF, Auto, TunE parameter in Cont menu. Press ASET/OK button for saving the parameter and turn to the main operation screen.
3- Observe that " _unE blinks in set display.

Note- For starting the Tune operation,

Heating Tune Operation:Process value must be lower than process set value at least 5 % of full scale

Cooling Tune Operation :Process value must be greater than process set value at least 5% of the full scale. If this condition is not okay, Blinks on the screen for 10 seconds.

Canceling Self Tune operation :

1- If sensor breaks ;
2- If Self Tune operation can not be completed in 8 hours;
3- While heating Self Tune is running, if process value becomes greater than Process Set value
