Installation
Terminal Strip Left Side TOP -
Open Collector Outputs
These outputs are open collector, floating TTL outputs.
There are no protection devices on these drivers. If the
transistor output is connected directly to +24 volts with
no load, these devices may be damaged. These drivers
are optically isolated from the local power supply and
their commons are floating. To utilize these drivers, Ter-
minal 43 must be connected to the common of the volt-
age supply for the device being driven (such as a PLC
input power supply, input common).

Safety Set (optional)
The Safety Set is a plug-in option that allows the opera-
tor to manually activate the function buttons from out-
side the enclosure.
1. Disconnect all power to the monitor.
2. Verify that the module is properly aligned and all
pins are in their proper sockets.
3. Place the magnetic Datawand over the Safety Set
target above the desired button to activate the func-
tion buttons (F . 8).
IG
The Datawand activates the sensor through the win-
dow and keeps it activated until the Datawand is
removed.

NOTICE
Use caution when handling and storing the Datawand. It
emits a strong magnetic field. Bringing the Datawand
near magnetic media found on credit cards, floppy dis-
kettes, or audio tape could destroy stored information!
