14 II. Sequence of Operation and Service Diagnosis A. Sequence of Operation Flo w Char t 1 . "E" and "G" Control Boar d without Harvest P ump Timer Operation Components Energized w.
15 1 . Bin F ull Shutdown Dela y: • Fill Cy c le –1 5 sec. af ter activ ation. • Harvest Cyc le –At the end of the har vest cy cle, or up t o 15 sec. into the freez e cy cle if activat ed at the end of the harvest cy cle. • F reeze Cycle –1 5 sec.
16 2. "G" Control Boar d with Harvest P ump Timer Oper ation 1 to 3-min. harvest timer in control (S4 dip s witch 1 & 2) • Maximum inlet wat er v alv e time: 6 min. or the length of harvest minus 50 sec. (S4 dip switch 7), whiche v er is shor t er .
17 B. Service Diagnosis W ARNING • The appliance should be diagnosed and repair ed only b y quali ed ser vice personnel t o reduce the risk of death, electr ic shoc k, serious injur y , or re .
18 1 . "E" and "G" Control Boar d without Harvest P ump Timer Diagnosis 3) P ow er On : T ur n on the power suppl y , then mov e the control s witch to the "ICE" position. A 5-sec. delay occur s. • "E" Contr ol Board: CB red "PO WER OK" LED tur ns on.
19 4) 1 -Minut e F ill Cy c le – LED 4 is on. WV energiz es . Af ter 1 min., CB chec ks for a closed FS. If FS is closed, har v est cy cle begins. If har vest c y cle begins (Comp , HGV , and FMR energiz e), continue to st ep 5. If FS is open, WV r emains ener gized thr ough additional 1 -min.
20 e) Initial Harvest Cy c le T ermination Diagnosis : W hen the ther mist or r eaches 48°F (9°C), CB reads 3.9 kΩ fr om the ther mistor and turns har vest t er mination ov er to the har v est timer (S4 dip s witch 1 & 2). Check dischar ge line temperatur e .
21 d) PM Diagnosis : Conr m wat er is o wing ov er e v aporator fr om PM and not WV . If PM de-energiz es once freeze begins , check f or 1 1 5V AC at CB K1 #4 (R) t o neutral (W). If 1 1 5V A C is not present, r eplace CB . If 1 1 5V AC is pr esent and PM is de-energized, check f or 1 1 5V A C at control s witch #5 (R) to neutral (W).
22 7) Pump-Out Cy cle – LEDs 1, 3, and 2 are on (1 0/20 second pump-out). Timing of the rst pump-out is dependent on CB . "E" CB rst pump-out is af t er the r st fr eeze c y cle. "G" CB rst pump-out is det er mined by S4 dip s witch 5 & 6.
23 9) Shutdown a) "E" Control Boar d: Thermostatic Bin Contr ol (TBC): When the appliance is running , hold ice in contact with the thermostatic bulb . TBC switch opens within 1 0 sec., shut ting down the appliance. TBC is f act or y set, and generall y no adjustment is requir ed.
24 2. "G" Control Boar d with Harvest P ump Timer Diagnosis 3) P ow er On : T ur n on the power suppl y , then mov e the control s witch to the "ICE" position. A 5-sec. delay occur s. CB red "PO WER OK" LED and gr een "BC CLOSED" LED turn on.
25 4) 1 -Min. Fill Cy c le – LED 4 is on. WV and X1 1 rela y ener giz e. Af ter 1 min., CB chec ks f or a closed FS. If FS is closed, the har v est cy cle begins. If har vest c y cle begins (Comp , HGV , FMR energiz ed), continue t o step 5a. If FS is open, WV r emains ener giz ed through additional 1 -min.
26 5b) Harvest P ump Timer – LEDs 1, 3, and 2 ar e on. When the thermistor r eaches 48°F (9°C), CB reads 3.9 kΩ fr om the ther mistor and turns har vest t er mination ov er to the har v est timer (S4 dip s witch 1 & 2). 50 sec. bef or e the har v est timer ter minat es , LED 3tur ns on and PM ener giz es.
27 6) F r eeze Cyc le – LED 1 is on. Comp , FMR, and PM continue . FM and LL V energiz e . HGV and X1 0 r ela y de-energize . Appliance is held in freez e b y a 5-min. shor t cy cle prot ection timer . Af t er 5-min. timer terminates and FS opens , fr eeze c y cle t er minat es .
28 f) Refr ig er ant P r essur es, HM, and TXV Diagnosis : If ev aporator is still not cooling , check r efr igerant pr essures. See "VIII.B . P erformance Dat a." Ne xt, chec k HM operation. If r efrigeration pressur es are abov e HM setpoint and HMis bypassing , replace HM.
29 is complete . The pump-out frequency contr ol (S4 dip switch 5 & 6) is f actory set, and generall y no adjustment is r equir ed. Howe ver , the pump-out frequenc y control can be set to ha ve a pump-out occur e very cycle , or e very 2, 5, or 1 0 cycles .
