5.0 Output Setup (alarm relays)
Below is the menu structure for the Output Setup selection. The layout of the Output Setup menu is similar to
the Input Setup menu. Outputs were designed to directly communicate to SCADA systems, alarms, data
loggers, backup pumps, pumps to operate in sync, pumps to operate proportionally, and other external devices.
To prevent false alarms due to pump start-up and closed loop applications, a trigger delay time can be config-
ured to delay the relay switch action. The delay time unit of measure is seconds.
4.7 Remote/Local Control
The MD3 can be configured for Remote control only, Local control only, or either
(disabled).
When set for Remote control only, all touch pad buttons except the menu button are
disabled. To completely lock out the menu, configure a password (see page 12,
section 8). If REMOTE ONLY is selected, the user is prompted to select an input
operating mode which must then be used when operating the pump.
When set for local control only, all input signals including the remote start/stop are
disabled. Note that the “contact closure input” menu setting (section 4.4) is
switched to “disabled” while
LOCAL ONLY is selected. This menu setting will return
to the previous setting when REMOTE ONLY or DISABLED is selected.

4.8 Set Revolution Alarm
The MD3 includes a revolution counter. A revolution alarm set point can be input
which will alert the operator when a programmable number of revolutions has been
reached.
When the set point is reached, the pump display will turn red and the words “REV
ALARM” will be displayed.
The pump will not stop.
An alarm output can be configured to close when the revolution set point is
reached.
Description of Relay and Contact Closure Output triggers
Selection: Contact energizes when:
Pump Run/Stop ........ Motor turning.
Monitor Input .... ........ Incoming analog or digital signal is not received or out of range.
Monitor Output .. ........Outgoing analog or digital signal not transmitted or out of range.
Monitor Run/Fail ........Motor fails to respond to commands.
Both DFD/FVS .. ........Either DFD or FVS system triggers.
FVS ........ ........ ........After the programmed delay time, pulses are not received from flow sensor.
DFD ........ ........ ........Diaphragm failure is detected by sensors.
Active Mode ...... ........Use to monitor any changes to the active (run) mode selection.*
Remote Active .. ........ Energized when Remote only is active.
Revolution Alarm....... Revolution count set-point has been achieved.
General Error.... ........ A motor overload or other internal error has occurred (includes DFD/FVS).
Disable ..... ........ ........Output contact is disabled.
