Effective November 2003
For example, if 10 PSI is programmed, each time the system
pressure fluctuates by 10 PSI, up or down, the actual pres-
sure is recorded in memory and printed, tagged with a date
and time. This method avoids continual, time-based printing
of unnecessary pressure values.
(If the pressure transducer is disabled in the controller
firmware, this function is disabled for either a standard
LMR or Foam Pump Controller.)
6.2.15 Current Pressure
Allows the user to view the actual pressure during
programming of the LMR.
(If the pressure transducer is disabled in the controller
firmware, and a remote device is connected to the Pump
Start input, the LCD Display will indicate “OK” if the input
contact is open, or “LOW” if the input contact is closed.)
6.2.16 Elapsed Time Meter
This parameter allows the user to reset the elapsed run time
value to zero. Display is in 1 hour increments.
The LMR monitors and records the run time of the motor,
in hours, via feedback of the main run contactor’s auxiliary
contact (terminals 33 and 49). The actual run time can be
viewed by the LCD display as described in Section 4.3 of
this manual.
6.2.17 Number of Operations
This parameter allows the user to reset the number of
operations count to zero.
The LMR monitors and records the number of start requests,
via feedback of the main run contactor’s auxiliary contact
(terminals 33 and 49). The actual count can be viewed by
the LCD display as described in Section 4.3 of this manual.
6.2.18 Sequential Start
This parameter allows you to program a start delay after a
start request. To bypass the start delay, set the parameter
to zero.
The programmable range is: 0-300 sec
6.2.19 Manual Stop
(For Foam Pump controllers refer to section 15.1 –
Stop Mode)
If ‘Enabled’, once started, the motor MUST be stopped
manually by depressing the STOP pushbutton located on
the flange, regardless of the starting cause. If ‘Disabled’,
the RPT becomes operative on automatic starts.
6.2.20 Overvoltage
This parameter will set the value at which the Overvoltage
LED turns on and the Common Alarm Relay, 3CR,
de-energizes.
The programmable range is: 5-20 %
6.2.21 Undervoltage
This parameter will set the value at which the Undervoltage
LED turns on and the Common Alarm Relay, 3CR,
de-energizes.
The programmable range is: 5-30 %
6.2.22 Print Routine
If selected for Auto, the messages will print immediately
without any user intervention.
If selected for Manual, the messages will be stored in the
controller’s memory and will print once the TIME/PRINT
key is pushed and held for 3 seconds. Refer to section 4.1.
To avoid paper build up inside the enclosure, it is
recommended that the print mode be selected as
‘MANUAL’ during normal operation of the controller.
6.2.23 Exiting the Menu
Pressing the Reset key at any time while in the menu system,
will exit the menu system and return to the automatic mode.
Any changes made to the program will be saved.
6.2.24 Print Status
If selected as ‘NO’, a Status report will not print when
exiting the programming menu. If selected as ‘YES’, after
exiting the program mode, and the Time/Print button is
pressed for 3 seconds, the programmed parameters and
selected controller readings will be printed.
A status report can also be printed when not in the
programming menu, by pressing and holding the
ACK.ALARM key for 3 seconds.
A sample status printout is shown below:
