3. Optical Sensors for Harmonic Model:
For the harmonic model, there are 4 optical cams to set the final limits, door protection monitor, and
an AUX. cam for the narrower door. The Optical cam board, 2500-3056, carries the optical sensors, and
the table below describes the functions of those sensors.
4. Hall-effect Sensors for Linear Model:
For the linear model, there are 4 hall-effect sensors to set the final limits, door protection monitor,
and an AUX. sensor for the narrower door. These hall-effect sensors have the same functions as in
the harmonic operator, as shown in the table above. They are connected to the signals transfer board
and arranged as follows:
Number

Label Remarks
1 DOL
Door Open Limit. The VFE2500 utilizes
the DOL limit signal for door width
learning. After the door width learning
process is completed, VFE2500 utilizes
the DOL limit as HOME position
whenever power is restored after an
interrupt.
2
AUX
NARROWER
Set Par. 199=0 to use the
AUX/NARROWER sensor as the DOL
input of the narrower door.
Set par. 199 = 1 to deselect the
AUX/NARROWER sensor.
3 DPM
DPM: Door Protection Monitor. The
DPM cam triggers the DPM Relay and
activates ½ inch before the Gate
switch makes.
4 DCL
Door Close Limit. The VFE2500 utilizes
the DCL limit signal for door width
learning. After the door width learning
process is completed, VFE2500 also
utilizes the DCL limit as HOME position
whenever power is restored after an
interrupt.
