Eberle EM 524 89 Assembly And Operating Instructions Manual - Menu Items:
Menu items:
Application:
Range: GROUND, ROOF
default value: GROUND
The application (gutter or ground)is selected with this setting. The application selected
will be retained when you revert to the default program.
Range:
Range: –5 … –20 °C (23 …–4 °F), OFF
default value: –10 °C
lower temperature limit.
This temperature value specifies the lower operating temperature limit. Up to this
temperature limit the ice detector operates in the normal mode (Heating ON, when the
switch on conditions are satisfied). Below this temperature the ice detector will be in
“Stand by” mode. If set to OFF, the ice detector works in normal mode at all
temperatures.
Attention: The temperature set here has priority over the set ground temperature.
Temperature:
Range: 0 … 6 °C (32 … 42.8 °F)
Default value: + 3 °C (37.5 °F)
If the temperature falls below this set value, the ice detector will switch the heater on if
the “moisture” menu item is switched off. If the moisture menu item is set at a certain
value the heating system will only be switched on when the temperature falls below this
value and the humidity is exceeded.
Moisture:
Range: 1 to 8, OFF
Default value: 3
The sensitivity to humidity is switched on and off here. If it is switched on, you can set a
value between 1 (almost dry) and 8 (very damp).
Note: If the heating switches off too early, even though conditions are still damp, you can
prevent this by adjusting the humidity level to 2.
Base temperature:
Range: –15 … –1°C (5 … 32.2 °F)
Default value: OFF
With this setting you can specify a temperature which the temperature of the area to be
heated must not fall below. When a temperature is set here, the ice detector will switch
the heating on immediately irrespective of the humidity, when the temperature falls
below this preset value. This menu item is hidden in the roof application.
Attention: The limit temperature set under the “range” menu item area has priority over
the set ground temperature.
Post purge:
Range: 10 MIN to 24 HRS, OFF
Default value: 20 MIN
You can set a subsequent heating time of between 10 minutes and 24 hours here. This
function can also be switched off.
Note: If there is still snow or ice remaining when the subsequent heating time has expired,
you can prevent this by increasing the subsequent heating time. Bear in mind the
increased heating costs should you do this
