SECONDARY OBSTRUCTION SENSING DEVICES
Another sensing device (Either a contact or a non-contact
system) must be installed and connected to this unit to
increase protection against entrapment per U/L
requirements.
NOTE:
All safety device contacts must be
NORMALLY OPEN.
NOTE: 24 VAC power is available at marked terminals for
devices that may require it (
i.e., photo eyes, wireless edges,
etc).
CONTACT SENSOR INSTALLATION:
NOTE: Wireless sensors must be installed so there is no
signal interference.
NOTE: All hard wiring to safety edges must be installed so
there is no threat of mechanical damage to wiring between
components, when the gate is moving.
1.
Install electric edge sensors in locations shown below.
NOTE: A separate pedestrian gate must be installed if there is
no other entry access but the vehicular gate.

2. Connect contact sensor edges to the control board as
shown in the illustration below.
NOTE: Leading edge is connected to “CLO EDG” and “COM”
terminals. Trailing edge, Post Mounted edge and Fence Mounted
edge are connected to “OPN EDG” and “COM” terminals.
3. After sensors are mounted and electrically connected,
turn on the power.
4. Test the close obstruction sensing system for proper
operation, by depressing the leading edge sensing
strip while the operator is running closed.
NOTE: The operator should stop and reverse a short
distance and then stop.
5. Run the operator to the close limit.
6. Test the open obstruction sensing system by
depressing one of the other three edge sensors while
the gate is opening.
NOTE: The operator should repeat the STOP AND REVERSE
procedure.
7. Run operator to the close limit and repeat step #6 for
the other two edges.
