9 SS In Flt I/O
Faults
(1)
An SS_In fault occurs if an error is detected in the SS_In dual-channel input.
10 SS Out Flt An SS_Out fault occurs if an error is detected in the SS_Out dual-channel output.
14 SLS In Flt An SLS_In fault occurs if an error is detected in the SLS_In dual-channel input.
15 SLS Out Flt An SLS_Out fault occurs if an error is detected in the SLS_Out dual-channel output.
20 DM In Flt A DM_In fault occurs if an error is detected in the DM_In dual-channel input.
22 DC Out Flt A DC_Out fault occurs if an error is detected in the DC_Out dual-channel output.
23 LM In Flt An LM_In fault occurs if an error is detected in the LM_In dual-channel input.
25 ESM In Flt An ESM_In fault occurs if an error is detected in the ESM_In dual-channel input.
16 SLS Speed Flt Motion
Faults The monitored speed was detected at greater than or equal to the Safe Speed Limit during Safe Limited Speed
monitoring.
17 SMS Spd Flt A Safe Maximum Speed fault indicates that Safe Maximum Speed (SMS) monitoring is enabled and the monitored
speed was detected at greater than or equal to the configured Safe Max Speed.
18 Accel Flt An Acceleration fault indicates that the monitored speed was detected as greater than or equal to the configured
Safe Accel Rate during safe acceleration monitoring.
19 Dir Flt A Direction fault indicates that motion was detected in the restricted direction during safe direction monitoring
(SDM).
21 Door Mon Flt Monitor
Fault If the safety option is configured for Safe Limited Speed (SLS), but SLS monitoring is not active, the DM_In input
must be ON (door closed) or a Door Monitoring fault occurs.
A Door Monitoring fault occurs if the door is open (DM_In input is OFF) when an SS Reset or SLS Reset is requested
(SLS_In transitions to ON).
If a configured SLS Monitoring Delay P53 [LimSpd Mon Delay] is in progress prior to Safe Limited Speed
monitoring being active and the DM_In input is OFF (door open), a Door Monitoring fault occurs.
If the safety option is configured for door monitoring and enabling switch monitoring and is actively monitoring
safe limited speed, a Door Monitoring fault occurs if the DM_In input transitions from ON to OFF (door is opened),
while the ESM_In input is OFF.
26 ESM Mon Flt If the safety option is configured for enabling switch monitoring and is actively monitoring safe limited speed, the
ESM_In input must be ON or an ESM Monitoring fault occurs.
If the safety option is configured for enabling switch monitoring only and a configured SLS monitoring delay
[LimSpd Mon Delay] is in progress, the ESM_In input must be ON when the delay times out or an ESM Monitoring
fault occurs.
If the ESM_In input is ON while the safety option is actively monitoring safe limited speed, the door can be
opened (DM_In transitions from ON to OFF) if no Lock Monitoring fault exists. However, if the ESM_In input
transitions to OFF after the door has been opened, an ESM Monitoring fault occurs.
If you attempt an SS Reset while the SLS_In input is OFF and the ESM_In input is OFF, an ESM Monitoring fault
occurs.
24 Lock Mon Flt If the safety option is configured for lock monitoring, a Lock Monitoring fault occurs when:
• the LM_In input is detected as OFF while the door control output is in the Lock state, except for the 5 seconds
following the transition of the DC_Out output from Unlock to Lock.
• the LM_In input is detected as ON when the DM_In signal transitioned from ON to OFF.
