L-PAK 150/250 Advanced
6.4 Standard Pilot Signal (PS) input
6.4.1 PS Input 2
Input 2, terminals 13 and 14 are for the standard pilot signal input. It is possible to set this input into 2 state
Standard or PSIFC mode.
Standard mode
Switch = Off: Filter cleaning by timer or manual cleaning is possible any time when PS is activated.
PSIFC mode
Switch = On: Filter cleaning by timer or manual cleaning is not possible when PS is activated.
Cleaning starts after PS = off.
ESC OK
PSIFC-I2 1/1
Switch = Off
Switch = off: Default setting.
6.4.2 PS Input 8
Default Advanced PSIFC (Pilot Signal Interlock Filter Cleaning)
L-PAK Advanced models are configured with Input 8 as a pilot signal input for the PSIFC filter cleaning process.
Input 8, terminals 11 and 17 act as pilot signal inputs and interlock the cleaning process. When this input is used
as a pilot signal input, filter cleaning cannot be activated until this PS input is deactivated. If this input activates
during a filter cleaning sequence, the filter sequence stops immediately and the unit establishes a vacuum.
Input 8 can be combined with input 2.
Example: Input 2 = (PSIFC-I2 = Off)
When PS Input 2 is used the filter cleaning can proceed any time but if Input 8 is activated the input will interlock
all filter cleaning attempts “Input 8 has the highest priority”.

is in Standby mode or the fan is running. The H1 lamp/Output DO1 is available on terminals X1:3 and X1:4 for re-
mote indication.
