The Clarus control unit automatically detects if weighing equipment is connected, and the actual (current) weight is shown on the display, on one line of the menu (normal display mode). When the machine starts to be loaded, the display switches to showing the actual weight in large numerals (weight display mode). Normal display mode is resumed if a new program number is entered, if the "SELECT" key is pressed, or automatically after the time set via "Settings 1" under "Time for weight display". While a wash program is running, you can switch to weight display mode by selecting "Show weight". The weight shown on the display will always be the net weight (achieved because the weighing equipment has been "tared").
Troubleshooting and error codes
| Error/Function | Error message displayed |
|---|---|
| 01 ERROR. NO WATER | Water level has not reached set level within time set. After this error message appears and the machine is reset, the machine will try again. |
| 02 ERROR. OPEN DOOR | Signal from microswitch which checks door status absent during program. After this error message appears and the machine is reset, the machine will try again. |
| 03 ERROR. DOOR LOCK | Signal from microswitch which detects when the door is locked absent during program. |
| 04 ERROR. LOW TEMPERATURE | The temperature is below the lowest value allowed (open circuit in temperature sensor). |
| 05 ERROR. HIGH TEMPERATURE | The temperature is above the highest value allowed (short-circuit in temperature sensor). |
| 06 ERROR. WATER IN MACHINE | The water level is higher that the level EMPTY at the start of the program. |
| 07 ERROR. OVER-FILLED | The water level is higher than the "LEVEL OVERFILL" (i.e. DRUM OVER-FILLED) level. If this function is switched off (=N), instead the drain valve will open for a short time and discharge some of the water. This is described under the function "DRAIN TIME WHEN OVERFILL" (i.e. DRAIN TIME AFTER OVER-FILLING) earlier in this section. |
| 08 ERROR. NO HEAT | The temperature has not increased by the number of degrees specified in the function "MIN. TEMPERATURE INCREASE" (see back in this section), over the period of time specified in the function MAXIMUM HEATING TIME (see "SETTINGS 1"). |
| 10 ERROR. REMAINING WATER | When the drain sequence has finished, the water level is still higher than the EMPTY level. |
| 11 ERROR. UNBALANCE SWITCH | The unbalance switch is closed when the machine is starting on a drain sequence. |
| 13 ERROR. MOTOR COMMUNICATION | Communication between PCU and motor control unit interrupted or disturbed. |
| 14 ERROR. LEVEL ADJUST | Every machine has individual level calibration at the factory. If these calibration values are missing or fall outside the limit values, an error warning will be flagged at each program start-up. The program can still be started, however, by pressing START. It will then use standard (default) values, which means that the levels will not be as precise as intended. |
| 15 ERROR. EMERGENCY STOP | The emergency stop button has been pressed. |
| 16 ERROR. WEIGHT FROM SCALE | Over-/Under-load of scale or weight above limit for maximum allowed weight at wash module start. |
| 17 ERROR. DOOR LOCK SWITCH | Even though the door lock microswitch indicates that the door is locked, the signal from the microswitch which is used to detect when the door is closed is absent. |
| 18 ERROR. START NOT ALLOWED | Network does not allow programme start. |
| 19 ERROR. MIS COMMUNICATION | Machine has lost contact with network. |
| 20 ERROR. INTERLOCK | Fault in MCU receiving circuitry for lock acknowledgement signal. The test of the MCU-interlock circuits proceeds in the following way: Before the locking of the door lock a speed command is sent from the timer to the MCU (=0 Hz). Then the timer checks that the value of the apparent current (ru 15) and output (ru 20) is below the value 5, which is a condition for locking the door. When the door is locked the timer again command running at 0 Hz and this time the apparent current and the output voltage shall have a value above 5. |
| 21 ERROR. I/O COMMUNICATION | Communication between the CPU board and one of the I/O boards interrupted or disturbed. |
| 22 ERROR. LOW OIL LEVEL | In machines with an oil lubrication system, indicates low level in the oil container. |
| 23 ERROR. LOW OR HIGH VOLTAGE | Incorrect input voltage to external equipment. |
| 24 ERROR. PRESSURE SENSORS, TILT | Both pressure sensors are active at the same time. |
| 25 ERROR. PRESSURE SENSOR TIMEOUT | No pressure at the relevant pressure sensor within the maximum time allowed for tilt backwards or forwards. |
| 26 ERROR. DOOR SWITCH, TILT | Door closed (S3) is "on" at a time when the machine door is locked open (S25). |
| 27 ERROR. LEVEL OFFSET | The pressure sensor for the water level signals a value that is so different from the empty machine state that the automatic level calibration cannot adjust the level system. |
| 28 ERROR. LEVEL NOT CALIBRATED | Calibration of level system not done in service mode before use of machine. |
