ATEST signal polarity (depends on the control panel)
SW4
↑
Negative
ATEST negative: ATEST signal is a fixed 12 or 24V signal
that the control panel sets to 0V to make the system check.
↓
Positive
ATEST positive: ATEST signal is disconnected and when the
control panel makes a testing gives a 12 or 24V signal.
In case of operating without ATEST signal, it is necessary to work in ATEST positive
way. In order to comply with the EN ISO 13849-1: 2015 safety standard, you must
connect this signal to test the system.
ON/WORK mode
The operating mode is selected by the SW2 of the receiver. This selector is neces-
sary when working with optical safety edges. All transmitters in the receiver work in
the same way. It will be necessary to reset the receiver when changing the operating
mode with transmitters already memorized.
With standard optical safety edges, WORK mode must be used due to high con-
sumption of the optical elements.
With OSE-S7502B and OSE-S7502 "always on" optical safety edges, both modes are
allowed. In ON mode, the system becomes universal for any control panel. In WORK
mode the battery life is maximized thanks to the shutdown of the optical elements.
