Pump A (CO2) primary temperature range error - WKB51218

Article number: 51218

SYMPTOMS

  • Error: Pump A (CO2) primary temperature range error (5.8 C)
  • Primary prechiller is out of tolerance (1.5-5 C)

ENVIRONMENT

  • ACQUITY UPC2
  • ccBSM

CAUSE

The prechiller for primary pump A (CO2) is unable to maintain temperature tolerance of 1.5-5 C due to low CO2 inlet pressure (less than 720 psi).

FIX or WORKAROUND

Investigate the CO2 source pressure (requirement is ~60 bar or 850 psi).

  • If the source is a tank, replace the CO2 tank with a full tank.
  • If source is in-house supply from bulk, check the pressure setting on the regulator or bulk source.
