Chapter 6 Safe Stop and Safe Stop with Door Monitoring Modes
Configuration
You configure the type of door control for each Safe Speed Monitor Option
module in the system.
A single or last safety option in a cascaded system can be configured for any Door
Output Type setting. For example, choose 2 Ch Sourcing to connect to a safety
programmable controller input. The first or middle safety option in a cascaded
system must be configured as 2 Ch Sourcing.
Effect of Faults
These fault conditions, which affect the integrity of the DC_Out output, will
force the DC_Out output to its safe state (OFF) regardless of the status of door
control logic:
• DC Out fault
• Invalid Configuration fault
• Internal Power Supply or MPU faults
For fault conditions where the DC_Out output can maintain its integrity, both
door control logic and the DC_Out output hold last state. If hold last state
cannot be maintained, faults may turn the DC_Out output OFF.
P57 [Door Out Type] Settings DC_Out Status and Lock State
Single and Last Units First and Middle Units
0 = Power to Release Not valid ON = Door is unlocked.
OFF = Door is locked.
1 = Power to Lock Not valid ON = Door is locked.
OFF = Door is unlocked.
2 = Cascading
(2 Ch Sourcing) 2 = Cascading
(2 Ch Sourcing) ON = Door is unlocked.
OFF = Door is locked.
ATTENTION: When the DC_Out output is configured as Power to Lock (P57
[Door Out Type] = 1), the safe state and faulted state is Unlocked.
Make sure that this possibility does not create a hazard.
IMPORTANT When the DC_Out output is configured for no pulse testing (P74 [Door Out
Mode] = 1) and the P57 [Door Out Type] setting is Power to Lock, and a reset is
attempted, the DC_Out output is pulsed low for 12 ms. During the 12 ms, the
door is unlocked.
ATTENTION: If a fault occurs after Standstill Speed has been reached, door
control remains unlocked.
