5.6 Diagnostics screen
To see additional diagnostics about a specic valve, advance a page to
the right using the arrows at the top of the more information screen.
1. The valve position information includes real time valve position,
stroke time baseline, and stroke time of last cycle (AS-i only -
ItemD).
2. The valve cycle count is displayed and indicates how many cycles
the valve has made since last reset (ItemE). A cycle is considered
to be a complete actuation of the valve. Selecting the reset button
(ItemG) will erase the cycle count and start counting again from 0.
3. The current temperature of the valve monitor is displayed; along
with the temperature range of the valve since last reset (ItemF).
Selecting the reset button (Item H) will erase the historical
temperature data and start a new period of temperature data
collection.
4. If external switches are connected to the Aux 1 or Aux 2 inputs of
the module, these switches can be monitored here. (AS-i only -
ItemJ)
5. If an external 4-20mA loop powered device is connected to the
auxiliary analog input of the module, the feedback signal can be
monitored here. (DeviceNet only - ItemK)
6. To verify intermediate control function (Expeditor only) select
expeditor override input (Item N). Change the existing percentage
in the associated text eld to desired value. Select done and verify
valve moves to indicated percentage displayed by valve position
(Item L) and override 4-20 mA input (Item M).
7. The Error Status register (ItemI) can display numerous faults that
are detected by the module. This data is only available via the
Wireless Link app and is not accessible from the bus network. The
following is a list of errors/faults that can be detected and display
on the iOS device:
