G. Secondary regulator pressure G. Insure CO2 regulator has not
creeping up. climbed above preset
30-32 PSIG (206.8-220.8 KPa).
H. CO2 check valve problem. H. Inspect CO2 check valve. Clean
or replace if necessary.
13.30 Max Fill A. Secondary CO2 pressure is A. Check Secondary CO2 for correct
set above 40 psi. setting of 28-32 psi (206.8-220.8
KPa).
B. Secondary regulator B. Insure CO2 regulator has not
pressure creeping up. climbed above 32 PSIG
(220.8 KPa). Clean or repair or
replace regulator, if necessary.
13.31 DefPRESmax A. Tank pressure above 55 psi. A. See 13.29.
13.32 DefProdOut A. Product supply is out during A. Replenish product supply
defrost stage. (i.e., water, CO2, syrup).
13.33 BTR-LO-ERR A. Product freezing too hard. A. 1. Check brix and correct, if
Beater % below 450. necessary.
2. Check Level Control and
correct, if necessary.
3. Check for restriction of beater
blades.
4. Check for failed beater motor.
B. Bad capacitor on motor. B. Check capacitor and replace as
required.
C. Motor control board failure. C. 1. Check connector from Beater
Motor to lower control board.
2. Change lower control board if
necessary.
13.34 Syrup Out A. Unit receiving no syrup. A. Check to see that syrup container
is not empty and is hooked up.
B. Restriction in lines. B. Assure all lines are free of crimps
or restrictions.
C. Regulator pressures (unit C. Check Syrups pressure readouts
and syrup pumps) too low. for 70-72psi. Adjust regulators, if
necessary.
D. Syrup Pump failure. D. Check pump and replace,
if necessary.
E. Excessive pressure drops E. Observe “Syrup Press” readouts
in syrup lines. as chamber fills to verify. Increase
line diameter or relocate syrup
source closer to unit. Syrup
pressures may only be raised (by
increasing pump CO2 pressure) if
separate regulators are installed for
unit and syrup pumps. Never
exceed pump manufacturer’s
recommended maximum CO2 inlet
pressure (see Section 12.4).
F. Syrup Transducer problem. F. Check syrup pressure readouts
for 70-72psi. If not within 2psi,
adjust regulator and/or check
transducer. Replace transducer, if
necessary.
G. Lower Board problem. G Test lower board for +5, +15, and
–15 outputs at J-5 plug (see
Figure 14.3).
H. Upper Board Problem. H. Circuits within Main Control (Upper)
Board electronics read transducer
pressures. Replace Main Control
(Upper) Board, if necessary
