3-5 External Device Monitor Function

This is the function for checking whether the external safety relay connected to the control output (OSSD
1 / 2) performs normally in accordance with the control output (OSSD 1 / 2) or not. Monitor the contacting
point "b" of the external safety relay, and if any abnormality such as deposit of the contacting point, etc. is
detected, change the status of the device into lockout one, and turn OFF the control output (OSSD 1 / 2).
● When the external device monitor function is set to be valid:
Connect the external device monitor input wire (yellow-green) to the external safety relay which is
connected to the control output 1 (OSSD 1) wire (black) and the control output 2 (OSSD 2) wire (white).
● When the external device monitor function is set to be invalid:
Connect the external device monitor input wire (yellow-green) to the auxiliary output wire
(yellow-green / black). At this time, the auxiliary output is set as [negative logic of control in
case the external device monitor input function is invalid, output (OSSD 1 / 2)] (factory set-
ting) [Set through the handy controller (SFB-HC) (optional)].
The auxiliary output cannot be connected to external devices.
<Reference>
It is also possible to set the external device monitor function into 'invalid' by using the handy con-
troller (SFB-HC) (optional).
