VIKINGTechnical Training2010

Initial Start-UpAs soon as power is applied.An audible beep will sound three timesThe TruProtect LED will flash an AMBER warning message that a power failure was detected.THIS IS A NORMAL CONDITION;All units are run through quality checks before leaving the factory. Power was disconnected from the unit when the compressor was still operating.Simply touch the ON/OFF keypad once to reset. The LED will turn a steady GREEN and the unit will operate normally.

Key Stroke ConfirmationAudible Beeps / AlarmsEach individual keypad stroke is confirmed by a short audible beep.When exiting the Diagnostics Mode, There will be a series of 3 longer audible beeps. When exiting the Sabbath Mode the audible beep will not sound.

Turn Unit On & OffPress & hold the ON/OFF keypad for 5 seconds for each functionThe display will be blank when the system is offThe TruProtect System has built-in locked rotor protection. The compressor, fans, and lights will all engage when the ON keypad is activated.

Adjust Set-PointTouch SET keypad to display current settingAdjust set-point by using the WARMER or COLDER keypadsSet-point mode will time out automatically in 10 seconds if no keypad activity occursExit set mode by pressing the SET keypad a second time

Display Actual TemperatureThe temperatures shown on the display readout are actual reading, not set point values.Display represents Real-Time monitoringUnlike some competitive productSome temperature fluctuation is normal depending on door openings, length of time into either an off or on cycle.

Selecting F / CPress the F / C keypad to switch to either Fahrenheit or Centigrade. Pressing the switch again will switch back to the previous setting.

Black-Out ModeThe display automatically shuts off when the door is closedThe display is hidden when door is closed

Interior LightingLight functionsActivated by door openings.De-activated by door closings.If the control has been turned OFF, the display will be blank. However, the lights will continue to function normally with each door opening or closing. The lights will time-out after 15 minutes if the door is left open. This prevents overheating

Display LightingDisplay lighting can be enabled by pressing the LIGHT keypad onceDisplay lighting is available on models with glass doors onlyDisplay lighting stays on continuously

Showroom LightingEnter the Showroom mode by depressing the ON/OFF keypad while performing a P-O-R (Power on Reset).An audible beep will sound when activated.The lights will disable after 15 minutes.To re-activate the lights, simply open & close the door.Exit the Showroom mode by performing a P-O-R only.

Showroom LightingWhen in the Showroom mode the compressor, condenser fan and compartment fan(s) alarms will be disabled.The following functions will remain enabled: The message center, the user interface panel and the internal lights.

Sabbath ModePress & hold the SET keypad while depressing the F / C keypad 4 times within 7 seconds.The display will flash 7 times as the unit enters the Sabbath modeThe display, message center, audible alarms, lights and all options will be disabledThe Sabbath mode will automatically time out in 72 hoursThe Sabbath mode can be exited by repeating the enable routineWhen exiting the audible alarm will not sound.

Sabbath ModeWhen in Sabbath Mode the compressor, condenser fan, and compartment fan(s) will operate through a delay timer built into the controls program. A random 10-25 second delay will occur at every call for either heat or cooling.If a door opening occurs, the same random time sequence will occur after the door is closed.Not K-STAR compliant Did not receive an official blessing from a Rabbi.

Sabbath ModeThe User Interface has a real time clock used for Sabbath Mode ONLY.This is used only during a power failure when in the Sabbath Mode.The clock is powered by use of the round battery located on the rear of the user interface board.

TruProtect SystemSystem monitoring is automatic unless it has been disabledThe TruProtect LED is located at the upper right-hand corner of the User Interface overlayThe LED will display a steady GREEN when the TruProtect system is enabled

TruProtect SystemDoor Ajar AlarmNo action required when TruProtect is enabledAudible alarm sounds 3-times every 30-seconds The TruProtect LED will flash GREEN

TruProtect SystemHigh / Low Temp AlarmNo action required when TruProtect is enabledAfter initial start-up, the system will automatically enable itself after the set-point has been reached or after 24 hours of operation.Alarm will engage if temperatures are outside a 10F parameter for over 1 hour after the system has enabled itself.

TruProtect SystemHigh / Low Temp AlarmAlarm may sound when changing set-points in access of 10F and/or high usageAlarm will sound 6-times every minuteThe TruProtect LED will flash RED

TruProtect SystemPower Failure AlarmNo action required when TruProtect is enabledAlarm will occur upon initial installationThe TruProtect LED will flash AMBER whenever power is interrupted. No audible alarm occurs

TruProtect SystemReset AlarmsClose door to reset door alarmPress ON/OFF keypad to reset all othersThe alarms will continue if condition still exists

To clear a display error, proceed with a POR (Power-On-Reset).If the fault is not corrected, the error will re-occur.

The Firmware 46 upgrade allows the technician to reset an error fault without unplugging or switching a circuit breaker.This can be accomplished as follows:Press and hold the Set keypad while pressing the On/Off keypad 4 times.Also unknown procedure for Firmware 44

TruProtect SystemDisable / Enable TruProtect SystemPress and hold SET keypad for 5 seconds to activate either modeThe TruProtect LED will display a steady GREEN when enabledThe TruProtect LED will display a steady AMBER when disabled

Fault CodesIf the parameters of the microprocessor exceed operating specifications the display will automatically flash the error code as follows:E1: Compressor faultE2: Condenser fan faultE3: Evaporator thermistor fault E4: Display thermistor fault

Fault CodesE1: Compressor Error CodeLow current condition = 470 mA 710 mAHigh current condition = 3.85 A 7.48 AAfter 10 seconds the compressor will shut downAfter 5 minutes the compressor will again attempt to restartIf will take three failed start attempts to display the E1 error codeThe Firmware 46 upgrade has improved tolerance of compressor error parameters. The E1 error codes no longer locks out the compressor.

Fault CodesE2: Condenser Fan Error CodeLow Current Condition

E3 and E4: Thermistor Fault CodesResistance at known set-point values4.63 k-ohms (40F)2.60 k-ohms (65F)Refer to resistance-temperature tables for additional values

DefrostNo mechanical or electrical defrost is available for TruProtect applications.Compressor off time during a typical cycle is sufficient enough to keep the evaporator plate clean.
