Filter condition OK: Relay contact closes between pin 04 and pin 05.
Filter saturation 75%: Relay contact opens between pin 04 and pin
05 – only LN/GL/CR-Series
Common relay contact for filter saturated inverted (pin 04) and for
filter saturated (pin 06) – only LN/GL/CR-Series
Relay contact opens between pin 05 and pin 06
Filter saturation 75%: Relay contact closes between pin 05 and pin
06 – only LN/GL/CR-Series
Control signal must by applied → not potential free!
Start/Stop via interface active if system in stand-by mode –
configuration not relevant (e.g. Pin 07 + / Pin 08 - )
On/off condition of the system: Run operation (PIN 09 a. PIN 10
open)
Stand-by operation (PIN 09 and PIN 10 connected)
speed O.K.: relay contact closes between pin 11 and pin 12
speed too low: relay contact opens between pin 11 and pin 12
Common relay contact for speed low (Pin 11)
Temp. O.K.: Relay contact closes between pin 12 and pin 13
Temp. too high: Relay contact opens between pin 12 and pin 13
By applying 3-10V DV (pin 14 and pin 15), speed can be controlled
external
For this, it is necessary to set the speed regulation at the device to
lowest value

80 without bedewing
Damaging effects of conditional bedewing can be prevented by a
special by-pass air guidance
In interior rooms only. Dust load of ambiance air must not bee too
high.
