Description
Default
Channel Type
Single
Inputs are treated as single channels. Dual-channel safety inputs can be configured as two
individual, single channels.
Single
Equivalent
Inputs are treated as a dual-channel equivalent pair. The channels must match within the
discrepancy time or an error is generated.
Discrepancy Time
0…65,530
(in 10 ms increments)
When Dual Channel mode is selected, this is the amount of time the two channels can be different
from each other (larger than the Deadband value) before a discrepancy error is declared. A
discrepancy time setting of 0 ms means that the channels in a dual configuration can be discrepant
for an infinite amount of time without a fault being declared, effectively eliminating the usefulness
of dual channel mode.
100 ms
Discrepancy Deadband
0…32767
(in engineering units)
In Dual Channel mode, when the paired input values exceed the deadband tolerance for longer than
the Discrepancy Time, a discrepancy fault occurs.
0
Channel Offset
-32768…32767
(in engineering units)
Offset value for dual channel mode only. Configure an offset when differences in the sensors
nominal input signals would otherwise exceed the desired deadband.
0
TIP
Configure a deadband value for applications that use two sensors to measure the
same variable; otherwise, spurious trips may occur.
