The motor of the HMD230/IGD has a pulse generator enabling the motor control
to determine the gate position. It is already connected to the control unit on
delivery. Limit switches are not necessary anymore.
4.7 SAFETY EDGES
Electrically driven Heras gates are protected by safety edges. The type of device
and the speed of movement depend on the motor control unit used. If the safety
device touches an obstacle, the gate will immediately stop and reverse.
Dependent on the device, the gate will restart. The safety edges have been fitted
to the stationary and/or moving part or parts of the gate. They are not required
for hold-to-run-control. These strips serve as safety components. The number of
safety edges depends on the situation.
Before the gate is moved, the control system checks the status of the safety
edges. If one of the safety edges is faulty, the gate can only be opened and closed
in hold-to-run-mode. In that case, consult a qualified engineer.
See the chapter “SERVICE /MAINTENANCE”
4.8 PHOTOCELLS
Photocells detect whether there are obstacles in the path taken by the gate. If an
obstacle is detected, the gate will stop immediately and slide open to its original
starting point (OPEN or PARTIALLY OPEN). Dependent on the device, the gate will
restart. The photocell is only active when the gate is being closed. Gates can be
fitted with multiple photocells.
