1794-IF8IH and 1794-OF8IH Configuration 41
Remote Low Low Alarm Limit (8 of 16 bit)
Sets the limit for the Remote Fault Low Low Alarm in 1 μ A steps. This affects
Data Formats 0…7. Steps apply to the 4…20 mA range.
For example, a value of 3600 will cause a Remote Fault Low Low Alarm below
3.6 mA (3600*1
μ A=3.6 mA).
Range: 0…22000 (0=disabled, 1*1 μ A to 22000*1 μ A)
Default: 0=disabled
