Frequently Asked Questions - ESO 97 S KATHREIN

What is the purpose of the ESO 97 S temperature controller?

The ESO 97 S is designed to control reflector heating (ESO 90/120/124/180 H) and feed system support heating (ESO 126 and ESO 129). It automatically switches on the heating when the outdoor temperature falls below a set value.

How does the temperature control work?

It is an electronic two-point controller with an adjustable temperature threshold. When the actual temperature (P01) drops below the target value (P10 minus hysteresis P11), the load relay activates the heating. An alarm relay provides error messages for over/under temperature or sensor faults.

What are the installation requirements for the ESO 97 S?

Installation must be carried out by qualified specialist personnel. The controller is mounted on the antenna mast using the provided tensioning strap, as high as possible. An earth-leakage circuit breaker with a nominal residual current of 0.03 A must be connected upstream. Ensure the power supply is disconnected during installation.

How do I set the target temperature?

Press the P key briefly to show the target value (Set). To change it, press and hold P for 3 seconds to enter the parameter list (P10). Use the arrow keys to select P10, then press P again to modify the value. Confirm by pressing P for 3 seconds. The default target value is +5°C.

What error codes can appear on the display?

E01: Sensor short circuit or temperature < -60°C. E02: Sensor disconnection or temperature > 410°C. E03: Third wire missing or resistance ≥ 10 Ω. C00: Protected parameters require code. Sensor errors appear after about 20 seconds delay.

How can I protect the settings from unauthorized changes?

All parameters except the target value (P10) are protected by a code. If the display shows C00, enter the required code number (C42) using the arrow keys and confirm with P. The code is requested again if no key is pressed for about 1 minute.

What maintenance does the ESO 97 S require?

Regularly check the attachment and function of the control device. For ambient temperatures above +5°C, use a cooler spray to simulate low temperature for testing. Apart from these checks, the unit is largely maintenance-free after installation.

What are the electrical specifications of the temperature controller?

Operational voltage: 208-230 V~, ±10%, 50/60 Hz. Switching capacity: 16 A / 230 V (80 A for 20 ms). Alarm contact: 8 A / 230 V. Measuring input: Pt100 temperature sensor.

Can the ESO 97 S be used with any heating system?

No, it is specifically designed for reflector heatings ESO 90/120/124/180 H and feed system support heatings ESO 126 and ESO 129. Using it with other systems may invalidate the warranty and cause safety hazards.

What happens if the temperature sensor fails?

If the sensor is disconnected or short-circuited, the display shows an error code (E01, E02, or E03) after a delay. Depending on the relay mode (parameter P34), the load relay either switches the heating off or on to prevent damage. The alarm relay provides a signaling contact.

Functional Description

The built-in electronic temperature controller serves as an air thermostat for recording the ambient temperature. It is fitted with cable glands and clamps for the power supply.

Function:

If the actual value (P01) falls below the target value (P10 minus hysteresis P11), the load relay switches on the heating. The integrated alarm relay provides error messages via a changeover contact in case of over-/under-temperature, sensor interruption or sensor short circuit. In case of sensor errors, the control relay switches the heating element off or on, depending on the controller configuration.

The heating is switched off if the sensor is disconnected or in case of a short circuit.

Operation

Operation is very easy. After switching on, the display shows the type number of the unit (C-2) and after about 3 seconds the measured actual value. If you press the "P" key briefly, the display shows "Set" and then the target value. After 5 seconds, the display automatically returns to "Set". Press the "P" key for about 3 seconds to get to the parameter list "P10". Press the "P" key for a further 3 seconds to display "dC" for degrees Celsius or "dF" for degrees Fahrenheit.

Call up and change parameters

To open the parameter list, press "P" for about 3 seconds until "P10" appears.

• Press "P" for 3 seconds: Parameter number is displayed
  ■ Press "▲/▼": Select the parameter
• Press "P" for 3 seconds: Parameter is displayed
  ■ Press "▲/▼": Change the parameter value
• Press "P" for 3 seconds: New value was saved, back to parameter number
• By keeping the “▲/▼” keys pressed, the values are progressing automatically. Press until “P1” or T>1 minute is displayed and exit the input mode

Protection against unauthorised access

The control target value can be set as desired, unless limited by P13/14. All other parameters are protected by a code.

If a code is required, the display shows "C00". Use the arrow keys to set the required code number (C42) and confirm with "P".

If no key is pressed for approx. 1 minute, the code is requested again.

Auto-scrolling

By keeping the “▲/▼” keys pressed, the values are progressing automatically.

Error messages

If an error occurs, the display shows an error code. Sensor errors are displayed with a delay of about 20 seconds.

P34 Relay mode (load relay K1 and signalling relay K2)

0 = Relay K2 (active) picks up in the case of sensor error, load relay K1 drops out in the case of sensor error
[1] = Relay K2 (passive) drops out in the case of sensor error, load relay K1 drops out in the case of sensor error
2 = K2 operates as release relay, load relay K1 drops out in the case of sensor error
3 = Relay K2 (active) picks up in the case of sensor error, load relay K1 picks up in the case of sensor error
4 = Relay K2 (passive) drops out in the case of sensor error, load relay K1 picks up in the case of sensor error
5 = K2 operates as release relay, load relay K1 picks up in the case of sensor error

P34 = 3, P34 = 4 and P34 = 5 is only permitted for anti-freezing applications and for use with self-regulating heating cables.

The values in square brackets [...] are the default settings.

Release relay mode

Relay K2 switches to this operating mode (P34 = 2 and P34 = 5) independently of P32 and P33 as soon as the actual value is within P30 and P31.

Alarm relay mode

(P34 = 0 or 1): If the actual temperature is below P31 when the device is started, P33 is used once as an alarm delay in order to give the system more time. In normal operation, P32 is used as an alarm delay.

Installation in outdoor temperature control mode

The controller is mounted on the antenna mast as high above the ground as possible using a tensioning strap. Recommended setting when used as an outdoor temperature control for reflector heaters: +3 to +5°C

According to the guidelines for outdoor installations, an earth-leakage circuit breaker with a nominal residual current of 0.03 A must be connected upstream.

Safe operation of the control unit requires that all components are properly installed and put into operation in accordance with the warnings given in these installation instructions.

Before starting the installation, check with the material list whether all parts are included.

Installing the temperature control

1. The control unit / terminal box with the pre-assembled installation kit is fastened to the antenna mast as high above the ground as possible using the tensioning strap. The exact installation height depends on the local conditions.
2. Place the steel strap around the unslotted screw. The length of the short end of the steel strap must be approx. one third of the mast tube circumference.
3. Cut the long end of the steel strap to the installation length, and cut to a point at the front. The installation length is determined by the mast tube circumference.
4. Insert the pointed end of the steel strap into the slot-headed screw and turn the screw head anti-clockwise. The steel strap now wraps around the tensioning screw and the universal jubilee clip is tightened. Tighten the nut to prevent the clip from coming loose. The universal jubilee clip can be released at any time and reused.

Electrical connection

1. Run the connection cable from the heating mats and feed system support heating along the antenna support to the ESO 97 S terminal box and fasten it with cable ties. In case the heating mat is fitted with a temperature sensor, this sensor cannot be used with the ESO 97 S. This sensor is used with the ESO 97 SL to determine the current heating temperature. ESO 97 SL enables energy-saving operation by additionally setting an upper switch-off temperature for the heating mat.
2. Insert the cable from below through the M16 glands (heating mats, feed system support heating) into the control unit / terminal box.
3. Insert the mains cable from below through the M32/M25 gland into the control unit / terminal box.

Test the heating for contact resistance and insulation resistance before connecting the cables in the control unit.

These tests should be repeated after replacing a defective heating element. For more information, refer to the operating instructions of the corresponding reflector heater.

1. The cables are connected according to the „Wiring Diagram“ on page 8.

For electrical connection, observe the voltage specified on the type plate. Non-observance can lead to destruction of the heating system by overheating or fire!

Connecting the earthing clamp

The earthing clamp is attached to the antenna mast near the terminal box as follows:

1. Place the tensioning strap around the mast. Make sure that the tensioning strap is tight around the antenna mast.
2. Pull the V2A strap through the clamp.
3. Tighten the V2A strap with the tensioning screw.
4. Connect the earthing cable to the earthing clamp.
5. Insert the earthing cable through an M12 gland into the terminal box (see illustration „Alarm relay mode“ on page 4).
6. Connect the earthing cable to the earthing terminal.
   ⇒ This ensures earthing of the entire electrical system.
