English
"PREHEATING MALFUNCTION" (Fig. 2, pos. 8)
The LED turns on red if the heating switches off or if the heating temperature switch or fuse is triggered.
"OIL PRESSURE MALFUNCTION" (Fig. 2, pos. 9)
The control lamp turns on red as soon as the oil pressure is detected to be too low by the automatic control of
the oil pressure. This error message can only be transmitted during diesel motor operation.
"WATER TANK LEVEL MALFUNCTION" (Fig. 2, pos. 10)
If the water tank level is too low, this LED turns on red.
"LACK OF MOTOR WATER MALFUNCTION" (Fig. 2, pos. 11)
The level of the cooling water is monitored. If the level is too low, this LED turns on red.
"START-UP TANK LEVEL MALFUNCTION" (Fig. 2, pos. 12)
The control lamp flashes red as soon as the level of the pump filling tank corresponds to 2/3 of the tank and
when the float switch is triggered. Once the start-up delay has elapsed (menu 1.2.5.2), the control lamp is
permanently turned on red. If at least the key switch is in the "Auto" position, the diesel motor starts
automatically.
"WATER TEMPERATURE MALFUNCTION" (Fig. 2, pos. 13)
The control lamp turns on red as soon as the temperature is detected to be too high by the connected
thermostatic valve. This error message can only be transmitted during diesel motor operation.
"VENT MALFUNCTION" (Fig. 2, pos. 14)
Once the diesel motor starts up, the aeration valves must open within 10 seconds. If no signal is emitted after
10 seconds, the LED turns on red.
"DIESEL LEVEL MALFUNCTION" (Fig. 2, pos. 15)
The control lamp turns on red as soon as the float switch of the fuel tank is triggered.
"ROOM TEMPERATURE MALFUNCTION" (Fig. 2, pos. 16)
As soon as the room temperature drops below 10 °C, the control lamp turns on red.
"START-UP ATTEMPT" (Fig. 2, pos. 22)
The control lamp turns on yellow when an automatic start-up of the motor has been triggered by the pressure
switch, followed by manual switch off, as well as after six consecutive failed start-up attempts.
"BATTERY LOAD 1/2" (Fig. 2, pos. 24, 25)
The two batteries are recharged alternately, every 24 hours. The corresponding green LED indicates the battery
which is being recharged.
"BATTERY MALFUNCTION 1/2" (Fig. 2, pos. 26, 27)
The voltage of the batteries is monitored. Furthermore, any absence of short-circuit or line break is checked. As
soon as a malfunction occurs, the LED turns on yellow.
"BATTERY CHARGER 1/2 MALFUNCTION" (Fig. 2, pos. 28, 29)
The connection voltage of the battery chargers is monitored. Furthermore, any absence of error or
communication malfunction is checked. As soon as a malfunction occurs, the LED turns on yellow.
