The ISD Connect has a similar current demand to the SI-RFD sensors. However, when used with a number of lighted ISD E-
Stops, the current draw of the E-stops governs the cable lengths and when more power is needed.
WARNING:
• Safety devices with OSSDs and without ISD, such as safety light curtains, are not compatible.
• Failure to follow these instructions could result in serious injury or death.
• Do not use safety devices with OSSDs and without ISD in a series connection of multiple ISD
devices.
Note:
• Safety devices with solid-state OSSDs are not acceptable Input Devices
• Failure to follow these instructions could result in serious injury or death.
• Only use safety devices with two normally closed (NC) contacts as input devices to the SSA-ISD
Connect.
2.6 Checkout
At machine set up, a
Designated Person

should test each safety point for proper machine shutdown response. A
Designated Person
should check the safety point for proper operation, physical damage, button looseness, and excessive
environmental contamination. This should take place on a periodic schedule determined by the user, based on the severity
of the operating environment and the frequency of switch actuations.
Adjust, repair, or replace components as needed. If inspection reveals contamination on the switch, thoroughly clean the
switch and eliminate the cause of the contamination. Replace the switch and/or appropriate components when any parts or
assemblies are damaged, broken, deformed, or badly worn; or if the electrical/mechanical specifications (for the
environment and operating conditions) have been exceeded.
Always test the control system for proper functioning under machine control conditions after performing maintenance,
replacing the safety point, or replacing any component of the device.
