Unit Operation The Randell BC series blast chillers are designed for rapid chilling through the danger zone down to 40 or below in approximately 90 minutes. The exact chill time will vary depending on product type. The door must be in closed position to activate switch at top of door before any cooling cycle will begin. 1.
as indicated above. Note: the unit can only be powered down while in the Idle Mode. 5. Chill Mode Operation a. The controller can run one of four possible chill modes, by either manual selection or automatically depending on certain prior conditions. This is explained more fully below: i. Idle Mode 1. This mode is automatically started when the On key is depressed. 2. This mode is returned to automatically when any chill modes have been stopped. 3. Operation: a.
3. Will start automatically from Idle or Hold mode if the following conditions are met: a. The Temperature Alarm (tALn) preset is set to “Auto” (Auto Start) and, b. The time since start of the Idle Mode is greater than the Auto Alarm Time (tALt) preset time and, c. One of the product probes is greater than the Auto Alarm Temperature (tALu) preset value.
Conditions. During this mode of operation, the Hold LED will flash. Note: Under certain settings, an Auto Defrost cycle may run at the end of this chill cycle just before the Hold cycle begins. During Hold mode, the display reading will default to Air Temperature. Once every minute, this reading will be briefly interrupted by the message “HOLd” for two seconds followed by an indication of the “time since the end” (of the chill cycle) for two seconds. e.
e. Once the timer elapses, an alarm will sound and the display will read “End” for approximately 10 seconds. The unit will then run the Hold mode which retains product temperature according to Product Set Point Conditions, i.e.
c. When the Defrost Cycle ends, the following may occur: i. If this cycle was initiated by an Auto or Manual chill cycle, it will begin a Hold mode. ii. If this cycle was manually started, it will begin the Idle Mode. d. Depressing the Stop key at any time will cease operation of the current mode and return the operation of the controller back to the Idle Mode. e. During this cycle, the Defrost Relay is “On.” f.
first time, the controller will prompt the user to set the RTC as it will automatically select and display the clock calendar menu. b. Setting RTC parameters is performed using a clock calendar menu that is similar to the preset menu: i. Depress the Down Arrow and the Select keys simultaneously. ii. The text “Cloc” & “CLdr” will be momentarily displayed, followed by the first clock /calendar parameter, time in hours: minutes format. iii.
b. Overview of Print/Log Operation: i. Data logging begins after an Auto or Manual “Timed” chill mode is initiated, either manually or automatically. ii. Chill data is acquired periodically and stored into log memory every five minutes. Data may also be stored immediately upon detection of specific Log Events. iii. “Live”chill information can be simultaneously obtained at the printer output, if enabled (Preset Prnt = On). iv.
c. Critical Time (*Critical-Time*) – Indicates the point in a chill process where the probe temperature passes through predefined temperature thresholds: i. 140F ii. 40F d. Power Restored (*POWER_RESTORED*) – Denotes the point where the chill process begins once power is restored from a previous power fault condition. e. Sample (*Sample*) – Periodic Time Stamp interval fixed at one sample every five (5) minutes. f.
segmented display: a. Last - Last Chill Cycle b. 24hr - Last 24 hours worth of Chill Cycles Depressing the Print key once more after the format selection is made will begin the print log process. During this time the Print LED will flash and the printer will begin to display log information in chronological order. Depressing the Print key two times consecutively will cancel a print dump that is in progress. ii.
i. With the unit powered off, depress the On/Off after depressing and holding the Select key to enter the product probe calibration menu. ii. Using the select key, scroll through each probe as indicated by Select LED indicators. iii. Use the up down arrows to add or subtract from the displayed probe reading.
