Adjusting the displayed temperature to match an actual thermometer reading.
Modifying advanced parameters requires entering the engineering passcode to prevent unauthorized changes to refrigeration cycles. Step-by-Step Programming Access
Incoming voltage is below the operational threshold. The controller isolates the compressor to prevent motor damage. 7. Preventive Maintenance and Best Practices Elstat Ems 25 Advanced Manual
For non-E-link units, wire the ALr relay output to a digital input on your PLC. Configure A1t (Alarm type) to rE (Refrigeration alarm) to get a dry contact closure during high/low temp events.
The primary temperature probe is shorted or disconnected. Check the wiring continuity at the low-voltage terminal block. Replace the NTC thermistor if resistance values do not match factory specifications.
Accurate sensor placement is crucial for reliable operation. : Navigates up through menu items or manually

Disclaimer: Always follow your facility’s lock-out/tag-out procedures before modifying any industrial control parameters. The settings above are suggestions based on typical applications; validate them against your specific process.
Compressor control output. Ensure the current draw does not exceed the rated relay capacity (typically 10A to 16A resistive). use the (internal pins marked +

The system uses two probes—a cabinet temperature probe (air) and an evaporator probe (defrost) 1.2.3 . Proper placement is critical to prevent, for example, the compressor from running continuously when it shouldn't 1.2.2 .
| Parameter | Inferred Value | |-----------|----------------| | Model | EMS-25 Advanced | | Type | Microprocessor-based PID/On-Off controller | | Power Supply | 230V AC ±10%, 50/60Hz | | Relay Outputs | Compressor (SPST 16A), Defrost (SPST 8A), Fan (SPST 5A) | | Sensor Input | 1 x NTC thermistor (10kΩ @ 25°C) | | Display | 3-digit 7-segment LED (-50°C to +150°C) |
The temperature swing allowed before the compressor turns on.
The EMS 25 is not an island. For advanced monitoring, use the (internal pins marked + , - , GND ). While Elstat does not promote standard Modbus on all EMS 25 units, late-production models support the Elstat E-link protocol .
