DXi User Manual
Appendix C: Current Alarms Within a Conventionlly Wired DXi System
A DXi will perform limit checking on Master Valves and pumps if current limit
checking is enabled and condemn if necessary.
All station, Master Valve and Pump related over/under current condemnations
(alerts) must be cleared for a given output, otherwise no activation will occur. A DXi
controller will block a program from starting if it utilizes a condemned Master Valve
or Pump. Manual operations will activate any output that is not condemned.
Current alarms are only generated at the satellite activating the output, all other
FLOWMAX participants will be unware of the alarm and will attempt to run their
automatic programs.
All satellites will report measured current and compared limit for each under/over
violation. Laguna will report the measured value, satellite compared limit and Laguna
max, min and nominal limits for station violations, but only the measured value and
satellite compared limit for MV's and Pumps.
Current Alarm Formats as Reported by Laguna:
1139 - Actual current is above maximum allowed current: MVx: actual current
exceeded allowed current <sat measured, sat maximum>
1141 - Actual current is above maximum allowed current: Px: actual current exceeded
allowed current <sat measured, sat maximum>
1120 - Actual current is above maximum allowed current: Sx: actual current exceeded
allowed current <sat measured, sat maximum> , <Laguna Min, Laguna Max, Laguna
Nom>
1005 (DX2) - Station Current too high: Sx: Station electrical current too high
<StationX, Pump, MVx, sat measured>, <Laguna min, Laguna Max, Laguna Nom>
1004 (DX2) - Station Current too low: Sx: Station electrical current too low
<StationX, Pump, MVx, sat measured>, <Laguna min, Laguna Max, Laguna Nom>
1140 - Actual current is below minimum allowed current: MVx: actual current below
minimum allowed current <sat measured, sat maximum>
1142 - Actual current is below minimum allowed current: Px: actual current below
minimum allowed current <sat measured, sat maximum>
1121 - Actual current is below minimum allowed current: Sx: actual current below
minimum allowed current <sat measured, sat maximum> , <Laguna Min, Laguna
