5.4.5 Sensor Monitoring
Monitoring can be selected through a function selector jumper (Presence Sensor Moni-
toring).
Test of Presence Detection is performed before opening. Test of Presence Impulse is
performed before closing. The Master Sensors are tested first and the slave sensors
are tested when the answer is received from Master Sensors.
If sensor test is not performed successfully the door will enter Manual Mode and
report sensor error. The sensor test will continue during manual mode.
It is only possible to monitor sensors with a normally closed (NC) output.
If the sensor error disappears during manual mode the door will re-enter automatic
mode again.
5.4.6 Overhead Presence Detection (OPD)
OPD impulse will prevent a closed door from opening and an open door from closing.
A moving door will ignore the OPD input. The OPD will be active 6 seconds after the
door has started to close. If a home switch is installed, the OPD will be active as soon
as the door is closed.
OPD can be selected through a function selector jumper (Sensor type OPD/Mat).
5.4.7 Mat Safety
Mat safety impulse will prevent a closed door from opening and an open door from
closing.
No impulses are accepted during closing if mat is activated.
Mat safety can be selected through a function selector jumper (Sensor type OPD/
Mat).
5.4.8 LockOut
LockOut is used to ignore the OPD sensor during opening and closing. Output will be
low (0 V DC) when the door is considered closed, high during opening and open and
toggling when the door is closing.
LockOut output will be low (0 V DC) when the door is manually opened.
5.4.9 Program selector
Program Selector PS-4C can be connected to the EXB.
The PS-4C, compared to PS-3B, has a fourth position EXIT that will make the CSDB
ignore the outer impulse device.
Presence sensors are enabled in all Program Selector settings but not when Kill Mode
has been activated.
