Analog Fault Signalling (2-state)
Note:
•
The factory setting FSH links menu 08 and menu 07, and sets them to enable fault
signalling
•
2-state mode must be selected at menu 07.
•
Menu 08 controls the current-loop fault/failure signal output. This signal has
precedence over the settings on Menu 07.
When 2-state fault signalling is enabled, in the case of a fault the mA output is 3.6 mA or
1
22 mA
, depending on the setting. The mA output is viewed at menu 07.

If the LCD displays an equal sign (=) in place of the colon (:) this indicates that
the loop-current is at fault/failure level. For example F: Hi becomes F= Hi.
Set the rotary switch to 8.
•
To change the mode to 2-state High, press the RED (+) button for more than a
second: the display reads F: Hi. In the case of a fault/failure the loop-current goes to
22.0 mA.
•
To change the mode to 2-state Low, press the BLUE (–) button for more than a
second: the display reads F: Lo. In the case of a fault/failure the loop-current goes to
3.6 mA.
Digital Output Signalling (solid-state output): menu level 1
To set values for Upper and Lower Threshold Delay, and Upper and Lower Threshold
Setting, the solid-state switch output must be enabled (menu 17). The factory setting,
FSH, links menus 17 and 18, to enable digital fault signalling. (When the solid-state switch
output is disabled

This option is only available if FPM is selected at menu 1E.
