Setup of the SITRANS WM300 MFA using the HMI of the device and four button keys.
Input Requirements
Input I1 – activates a "Reset" of all outputs after an alarm.
Input l1 can be used in the two applications listed below:
● Automatic Reset of any or all output(s) when a process variable is within defined upper
and lower limits as programmed for an input.
Note
Input I1 is set Active Hi and maintained at all times.
● Manual Reset of any or all output(s) when a defined upper or lower limit is observed and
the Alarm flag set. The physical output, once activated (failsafe operation, set to Lo) will
set the output relay to "Off" or "Low" and maintain this state until the operator physically
resets "Alarm On" by switching input I1 from Lo to Hi state using a "Momentary Make
Contact".
Note
Input I1 must transition momentarily from a Lo to a Hi to initiate the Reset function.
Input I2 – initiates a Start Up time delay when activated (Momentary transition from Lo - Hi -
Lo).
Gives operator the ability to program a time delay to allow a slow running process to achieve
the normal operating speed (typically for Slow Speed applications) before standard process
monitoring takes over.
