3. Short Stop
PCM applied to one gate is ideal for securely locking two gates to each other
without having to fit endstops. Typically, a 'mechanical' lip is fitted to one
gate which will push up against the other gate and via PCM keep pushing
until the gates are mechanically locked. To ensure that the gates do not close
past their desired end point, the Slave Gate against which the Master gate
with the mechanical lip pushes, can be preset to stop slightly short of its
closed position. This is referred to as the 'Short Stop' distance. If the 'Short
Stop' distance is correctly set, the Master Gate will engage with the Slave
Gate sufficiently before the closed position and via the PCM, push the two
gates into the fully closed position, but not past it.
4. Short Stop value
The Short Stop distance can be set
between 1mm and 40mm of
piston stroke.
5. PCM push force
The amount of force applied by
the actuator when in PCM can be
set as a value from 1 to 15.
6. Leaf Delay
Leaf Delay is used in cases where
one gate leaf must move before
the other. The most common need
for this arises when a mechanical
'lip' is fitted to one of the gates.
In a double leaf installation, a Leaf
Delay can be set whereby the
MTRM Motor will open before the
MTRS Motor and the MTRS Motor
will close before the MTRM Motor.
7. Leaf Delay value
The Leaf Delay is based on piston
position, and can be adjusted from
3mm to 250mm of piston travel.
8. Pre-open Delay
Allows a delay between a valid
trigger signal being received and
the gate commencing movement
in the opening direction.
A Warning Light can be set to
activate during this delay. (Refer
to Pre-flash Modes of the feature
‘Pillar Light, for more details.)
This setting applies to both
motors.
