Safe Limited Speed with
Enabling Switch Monitoring
Mode When properly configured for Safe Limited Speed with Enabling Switch
Monitoring, the safety option performs Safe Limited Speed (SLS) monitoring
functions as described in
Safe Limited Speed (SLS) Mode on page 75 in addition
to the Safe Stop functions as described in Safe Stop Mode on page 61 .
In addition, the safety option monitors the Enabling Switch Monitor input
(ESM_In) after the Safe Limited Speed Monitoring Delay [LimSpd Mon Delay]
times out. Once the enabling switch is activated, the ESM_In input must remain
ON while Safe Limited Speed monitoring is active or an ESM Monitoring fault
occurs. An ESM Monitoring fault is a Stop Category fault, which initiates the
configured Safe Stop Type.
