direction may be adjusted with the CLOSE
SENSITIVITY preset. (Pic 37)
If it is required to increase the obstruction
sensitivity, thus reducing the door edge pressure
required to activate the control unit obstruction
sensing circuit, which causes the door to stop and
re-open during the close fast speed cycle, then the
CLOSE SENSITIVITY adjuster should be turned
further clockwise. (Pic 38)
Note that this will also increase the possibility of the
controller reacting to slight abnormalities or minor
damage to the track or misalignment of track
sections. This may cause fluctuations in the motor
current and may be significant enough to result in
the door stopping and re-opening. It is therefore
important that the smooth movement of the door
is tested by releasing the manual over-ride lever and
moving the door by hand in both directions.
Both preset controls are factory set to the 12
o-clock positions. Providing the door runs
smoothly by hand in both directions it is unlikely
that the presets will require adjustment.
If either of the preset controls is adjusted, the
compression of the door edge seal will be affected
and thus the position of the fully closed door may
be different to the calibrated reference. In which
case it may be necessary to complete a new
Calibration Reset procedure.
SAFETY CIRCUIT WIRING
If the door is to be operated without any
supplementary safety devices then the STANDARD
SAFETY SWITCH, DIP switch No. 2 and the 12 volt
Photo-Eye, DIP switch No. 3 should be set to the
OFF position.
If a safety device such as a Standard Photo-Beam
(Photo-Eye) or Safety Edge is to be fitted then the
STANDARD SAFETY switch, DIP Switch No. 2 should
be set to the ON position. This provides a Safety
STOP and RE-OPEN control of the door if the safety
circuit becomes active whilst the door is closing.
If a Photo-Eye with a Normally Closed relay circuit
is fitted, then the relay contact wires are
connected to the SAFETY terminals at the top
right hand side of the panel. (Pic 40)
