P0t

   Pump Over Temperature: Select 

AUt0

 or 

rES

      When pump temperature sensor indicates that 

      there is an over temperature condition the pump will 

      be held out of service and the corresponding pump 

      over temperature lamp is lit on the controller. If 

      using the MPC with two pumps and lead/lag on

      then the remaining pump becomes the lead pump. 

      If lead/lag is turned off then the remaining pump 

      becomes controlled by Set Point 1. See page 8.

   

AUt0

    The pump will be automatically placed back 

              into service and the lamp turned off when 

              the over temperature condition has ceased.

   

rES

     The pump will remain out of service and the 

              lamp lit until the corresponding manual reset 

       

P10t

 or 

P20t

 is reset in the Secondary menu. 

              The pump cannot be brought back into 

              service until the over temperature condition 

              has ceased. 

 

PSF

   Pump Seal Failure: Select 

AUt0

 or 

rES

. See pages 

      7 and 8.

   

AUt0

    When pump moisture sensor indicates that 

              there is a seal failure condition the 

              corresponding pump seal failure lamp is lit 

              on the controller. The pump will remain in 

              service with only the lamp indication of 

              failure. The lamp will automatically turn off 

              when failure condition ceases.

   

rES

     When pump moisture sensor indicates that 

              there is a seal failure condition the 

              corresponding pump seal failure lamp is lit 

              on the controller. If the MPC is being used 

              with two pumps and the lead/lag feature 

              turned on then the failed pump will 

              automatically become the lag pump, the 

              remaining pump the lead pump, and the 

              alternation discontinued. The seal failure 

              action  is  reset  manually  with  the  values  of 

 

       

P1SF

  and 

P2SF

  in  the  Secondary  menu.  The 

 

              control will only reset if the pump moisture 

 

              sensor is no longer in a failed condition. 

tESt

  System Test: Select 

0n

 or 

0FF

. When 

0n

 is selected 

      the ˝System Test˝ key on the front panel will be 

      activated. By depressing this key for 3 seconds the 

      controller will simulate an input from 

SCAL

 to 

SCAH

 

      and back to 

SCAL

 over a period of 32 seconds. This 

      test will run continuously until the SYSTEM TEST 

      key is pressed again. When the controller is in 

      System Test Mode the lamp above the System Test 

      Key will be ON.
