6.3.2 Connecting the ISK system
The ASO ISK system has already been integrated with the HMD230. A stationary
SPK55 core can be connected to the lower of three 3-pole M8 buses. If relevant,
the core can also be connected to the plug-in terminal in the upper right-hand
corner of the input terminal block. These safeties are never connected to the
backplane, always directly on the control itself.
Attention: Connecting the M8 connector and the input terminal to one and
the same input at the same time is not allowed here either. This would
result in a parallel connection of the anti-crushing safety protection device, leading
to failures.
By default, the evaluation of a connected ISK system is activated. To
subsequently activate the ISK system (deactivate JCM), you can open the
"Settings" menu; "Securities" the menu item "Activate ISK" should be selected.
6.3.3 Connecting a photocell
Both one-way and reflective photocells of a 24V operating voltage can be
connected to the HMD230. Photocells can also be connected to the backplane; see
appendix B and C.
