Frequently Asked Questions - ESM-3711-CN Emko

How to change the setpoint temperature?

On the main screen, press the SET key to display the setpoint, use ▲ or ▼ to modify it, then press SET again to save. The value is displayed with the S LED on.

How to start a manual defrost?

Make sure the defrost time parameter dt is ≥ 1 and the key protection PrE is 0 or 2. On the main screen, press and hold the defrost key for 3 seconds to start or stop defrost. The defrost LED turns on.

What to do when 'Sbr' appears?

The flashing Sbr (or Err) message indicates a probe fault. Check the temperature sensor connection (NTC or PTC) and replace the probe if necessary. The internal buzzer may sound if configured.

How to access programming mode?

From the main screen, press and hold the SET key for 5 seconds. If a password is set (P-C), enter it with ▲/▼ then confirm with SET. If the password is 0, you access the parameters directly.

How to set the temperature alarm limits?

In programming mode, set the ALS parameter to choose the alarm type (absolute or relative). Then define the thresholds _uL (low alarm) and _uH (high alarm). The alarm delay is set with _u d and the startup delay with _u o.

Can I use the controller with an NTC or PTC probe?

Yes, the device accepts both types. The sensor must be specified at ordering (code BC = 18 for NTC, 12 for PTC). The supplied probe matches the chosen type. Measurement ranges are -50 to 100 °C (NTC) and -50 to 150 °C (PTC).

How to protect settings from modifications?

Use the PrE parameter (key protection) in the programming menu. Values range from 0 (no protection) to 4 (full protection). You can also set a password (P-C) for menu access.

How to use Modbus communication?

In the programming menu, set Con to 1 to select RS-485. Define the slave address Sid (1 to 247). The Modbus RTU protocol allows reading registers (temperature, status) and writing parameters.

What are the compressor protection delays?

Three configurable delays: PoS (startup delay), SPd (stop-start delay) and Std (start-start delay). Each can be set from 0 to 20 minutes to protect the compressor.

How to clean the device?

Use a soft cloth moistened with ethyl alcohol or water. Never use hydrocarbon-based solvents (gasoline, trichloroethylene) which could damage the plastic enclosure.

1. 56r Screen Blinking

Sensor failure. Sensor connection is wrong or there is no sensor connection. If buzzer function selection parameter buF is 3 or 4, internal buzzer starts to operate.

2- Blinking the Screen Value

If temperature higher than the alarm parameters limit, value on the screen starts to blink.

Example-1: If alarm function selection parameter [ALS] In programming section is 1(Absolute alarm) and minimum alarm parameter [RU-L] is 20;

When temperature is less than 20^ C, value on the screen starts to blink. Also if buzzer function selection parameter _uF is 2 or 4, then internal buzzer is on.

Example-2 : If alarm function selection parameter ^RLS in programming section is 1 (Absolute Alarm) and maximum alarm parameter ^RH is 50

When temperature is above 50 °C, value on the screen starts to blink. Also buzzer function selection parameter F is 2 or 4, then internal buzzer is on.

All order information of ESM-3711-CN Cooling Controller are given on the table at left. User may form appropriate device configuration from information and codes that at the table and convert it to the ordering codes. Firstly, supply voltage then other specifications must be determined. Please fill the order code blanks according to your needs.

Please contact us, if your needs are out of the standards.

Note-1: If input type is selected PTC or NTC (BC= 12, 18), Temperature sensor is given with the device. For this reason, if input type is selected as PTC, sensor type (V = 0,1 or 2) or if input type is selected as NTC, sensor type (V = 0,3 or 4) must be declared in ordering information.
