Functional description
Using the ESO 120/124/180 electric heaters prevents the build-up of snow, ice and frost on the antenna reflector surface, thus avoiding
faults with reception.
The control unit described in detail below performs the following tasks:
●Automatic activation of the heating in the event of snow, ice or frost build-up
●Automatic deactivation of the heating if the reflector temperature exceeds the set value
●Manual activation of the heating is possible (failure of sensors/electronics, test operation in summer)
●Operating condition display
●Potential-free indication of faults
Brief description of controller
All electrical components are located in a light, dust and moisture-proof polycarbonate housing.
When the housing cover is opened, all components are accessible with contact protection. The terminal strip connects all the
incoming and outgoing cables (sensors, heating, power supply) to the electrical components.
Operating mode: Automatic
The electronics switch on the power circuit if:
- The ambient temperature and heating temperature fall below the set value P(+4 °C SRR; factory setting: +40 °C ELTC-21), and
- The sensor electrodes detect moisture, snow, ice or frost on the antenna surface.
The heating switches o when one of the above conditions is no longer true. However, the integral timer function can be used to set
a post heating time between 1 and 10 min (factory setting: 5 min). The post heating time thus covers a short period during which the
sensor signal drops out, perhaps due to a brief burst of sunshine or to the influence of wind on one of the sensors. Pressing “POWER
OFF” resets the post heating time.
When the load circuit is activated, the operating RGB on the SRR lights up in yellow to indicate “AUTOMATIC HEATING ON”.
Operating mode: Manual
In “MANUAL” mode, the electronics are bypassed apart from the ELTC-21 function. The load circuit is switched on and the operating
RGB on the SRR flashes yellow to indicate “MANUAL HEATING ON”
Manual mode can also be activated using the remote operation signal (5 - 30 V). In “MANUAL” mode, if a sensor has a fault for
example, the heating continues running with temperature control using the ELTC-21 heating controller.
This enables the function of the heating to be checked during the summer months.

Functional description
Two electronic control units are installed in the ESO 99 S controller housing.
The frost controller (SRR) is used to detect the ambient conditions and the heating controller (ELTC-21) is used as a surface thermo-
stat with remote sensor for detecting the heating temperature. Cable glands and terminals are installed for the electrical connection.
SRR frost controller function (device 1)
The SRR frost controller detects the ambient temperature and also detects any frost, snow or ice build-up on the antenna surface.
PT100 sensors are used to detect the ambient temperature. The limit value is factory set to a fixed +4°C. Frost and potential ice build-
up are only expected at temperatures above this value. The coat forming on the monitored surface is registered using a 2-rod probe. A
window function in the SRR 200 enables the parameters to dierentiate between water and ice to be set.
These parameters are determined once and cannot be changed without the corresponding software.
If both conditions are met (temperature below +4°C and ice build-up detected), the heating controller is enabled by a potential-free
switching relay in the SRR 200 and heating of the antenna surface begins. As soon as one of the two conditions is no longer met,
the post heating time begins (the time is adjustable using potentiometers on the front panel of the SRR). The heating process is only
ended when the post heating time has elapsed. If the conditions are met again during the post heating time, the post heating time is
(automatically) reset and the control process starts again.
The heating controller keeps the antenna temperature at the set limit value (factory setting +40 °C). A control input allows the heating
controller to be enabled manually.
The USB port is used for communication with a computer. The frost controller can be set using the SRR 200 Config Tool parameter
setting software. Monitoring is also possible. The instructions for using this software can be found in the “SRR 200 Config Tool” oper-
ating manual.

ELTC 21 heating controller function (device 2):
If the actual value (P01) is lower than the setpoint (P10 minus hysteresis P11), the power relay switches on the heating. The integrated
alarm relay has a changeover contact that allows fault messages in the event of temperature too high / low, sensor failure or sensor
short circuit. In the event of sensor faults, the control relay switches the heating cable o or on depending on the controller configu-
ration. If the sensor fails or there is a sensor short circuit, the heating is switched o.
Operation is very easy. After switching on, the device type number (C-2) appears, followed around three seconds later by the meas-
ured actual value. Briefly pressing the “P” button displays “Set”, followed by the setpoint display, which automatically reverts after
5 seconds. Pressing the “P” button for around 3 seconds opens the parameter list “P10”. Holding down the “P” button for a further 3
seconds displays “dC” for degrees Celsius or “dF” for degrees Fahrenheit.

P34 Relay mode (power relay K1 and signal relay K2)
0 = Relay K2 (active) energised on sensor fault, power relay K1 de-energised on sensor fault
[1] = Relay K2 (passive) de-energised on sensor fault, power relay K1 de-energised on sensor fault
2 = K2 operates as release relay, power relay K1 de-energised on sensor fault
3 = Relay K2 (active) energised on sensor fault, power relay K1 energised on sensor fault
4 = Relay K2 (passive) de-energised on sensor fault, power relay K1 energised on sensor fault
5 = K2 operates as release relay, power relay K1 energised on sensor fault
P34=3, P34=4 and P34=5 is only permitted for frost protection applications and when using self-regulating heating cables.
The values in square brackets [...] represent the factory settings.
Release relay mode
In this mode (P34=2 and P34=5), relay K2 switches independently of P32 and P33 as soon as the actual value lies between 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 the alarm delay to give the system
more time. In normal operation, P32 is used as the alarm delay.
Commissioning
Reliable operation of the controller requires all components to be installed and started up properly taking
into account the warnings set out in these installation instructions.
Before starting the installation, check the material list to ensure that all parts have been supplied.
1. Use the installation instructions and circuit diagrams supplied to check that the installation is correct.
2. Before connecting the connecting cable in the controller housing, test the heating for continuity and insulation resistance (Ri)
(see installation instructions for the heating). These measurements (Ri) should be repeated after replacement of a defective
heating plate.
Heating functional test
1. Measure the mains input voltage: 230 VAC + 6/- 10%
2. Green “Status” and “Operation” LEDS light up
3. Set switch 1S1 to “Manual ON”
4. Yellow “Heating Manual” LED flashes
5. Measure the heating circuit voltage and heating circuit current at terminals X1: 1-10.
During this time, the ELTC-21 monitors the heating temperature.
Change the heating temperature setting on the ELTC-21 to +10°C.
The contactor 1K1 is de-energised.
Set the old value (+40 °C) and the contactor K1 is energised again.
After the measurement has been performed, set the switch 1S1 to the “Auto ON” position. The “Heating Manual” LED goes out after
the set post heating time
has elapsed.
Controller functional test
1. The “Status” and “Operation” LEDs on the SRR light up green
2. Cool down the ambient temperature sensor to below + 3°C using iced water or coolant spray.
The status LED must light up white for “Temperature”.
Touch the two rod electrodes with wet hands.
The status LED must now light up blue for “Ice”.
The operating LED must now light up yellow for “Heating Auto”.
The contactor 1K1 is energised and the operating hours counter must be running.
3. As soon as the “Ice” or “Temperature” condition is no longer met, the set post heating time (1 - 10 min) starts running. This value
can be changed on the potentiometer on the SRR using a screwdriver. When the post heating time has elapsed, the contactor 1K1
is de-energised.
4. Fault detection and signalling
- Disconnect the sensor cable from the “Ambient temperature” PT100. (Open the cable connection at terminal 3 on the SRR
control unit). The operating LED flashes red for “Alarm”.
- Disconnect the sensor cable from the “Reflector temperature” PT 100 (open the cable connection at terminal 17 on the ELTC-21
control unit). Fault signal E02 appears in the display.
For both faults, the alarm contact at terminal X1, 11 / 12 opens (closed circuit principle).

Cable from the reector and
feed system support heating
1. Run the connecting cables for the heating pads, feed system
holder, heating sensor unit and heating pad temperature
sensor along the antenna support to the control unit and
secure with cable ties.
2. Feed the cables into the control unit / connection box from
below through the M16 cable glands (heating pads, feed
system holder heating) and M12 cable glands (temperature
sensors, sensor unit).
3. Feed the mains cable into the control unit through the M32/
M25 cable gland from below.
Before connecting the cables in the control unit, check
the heating for continuity and insulation resistance.
These measurements should also be performed after
replacement of a defective heater. Refer to the oper-
ating instructions for the corresponding reflector
heater for details.
4. The cables are connected as shown in the “Connection
diagram” on page 11.
Only connect the electrical system to the voltage spec-
ified on the rating plate. Non-compliance can destroy
the heating due to overheating or fire.
Connecting the earth clamp
The earth clamp is attached close to the terminal box on the reflector mast as follows:
1. Tension the strap around the mast. Make sure that the strap is securely attached to the antenna mast.
2. Pull the V2A strap through the clamp.
3. Tension the V2A strap with the tension screw.
4. Connect the earth cable to the earth strap clamp.
5. Feed the earth cable through an M12 cable gland in the terminal box.
6. Connect the earth cable to the earth terminal.
➯This guarantees earthing of the entire electrical system.

Maintenance recommendation
Controller
We recommend performing a regular complete functional test of the system, preferably before the onset of winter, to check that the
entire antenna heating system is operating correctly (see “Controller functional test” on page 6).
Sensor system
Once a year, preferably before the onset of winter, the sensors should be wiped over with a moist cloth to remove any heavy dirt.
Heating plates / heating pads
The heating plate or heating pad should be checked for damage at regular intervals to ensure they are in sound condition. Other than
this, the heaters are largely maintenance free once installed.
