Figure 9 - Door Control Cascading Outputs
Only these wiring configurations, shown below, are supported for the Door
Control output.
Figure 10 - Door Control Output Wiring
(1) When wired as a source for a safety input, current is limited to 20 mA per output.
(2) For example, SmartGuard 600 controller, Guard I/O module.
Short-circuits of the output loop to ground or 24V will be detected. For cascaded
outputs, cross loops will also be detected.
The outputs are pulse-tested when the P74 [Door Out Mode] parameter is
configured for pulse-testing.

IMPORTANT If you disable pulse-testing on this output, the achievable SIL, Category, and PL
ratings of your entire safety system are reduced.
