In the table below is shown an overview of display indications.
*) Indication shown when a Twin-3 display has been connected to a Twin-2 pump.
NOTE
The display is equipped with a light-sensitive cell. Therefore the light intensity of the LED’s is
automatically dimmed when the surroundings become darker. Annoying reflections in screens of
the cabin are reduced to a minimum.
2.8.1 Decimal dot of the 3-digit display
Indication Explanation
When ignition is switched ON the 3-digit display forms an rotating clock
indicating it’s communication with the pump control unit. After 10
seconds the preset duty mode selection appears along with the green LED.
+
Light duty - Greasing mode with long intervals.
(Decreased greasing output)
+
Medium duty - Greasing mode with medium intervals.
(Normal greasing output)
+
Heavy duty - Greasing mode with short intervals.
(Increased greasing output)
+
*Pump performs a single cycle test (LED flashes slow).
(See paragraph 3.2).
+
*Pump performs multiple cycle test (LED flashes fast).
(See paragraph 3.3).
+
Pump performs a number of fast automatic cycles.
(See paragraph 3.4).
<>
When the pump is performing fast automatic cycles (without pressure
retaining, pressure decrease and pause phase), the display alternates
(every 5 seconds) between T3 and the number of remaining cycles. (In this
case ‘047’).
+
*Minimum level in the reservoir has been reached.
Resets itself by refilling the reservoir.
System error. Duty cycle selection possible only after the error has been
solved. (See “Malfunction reports of Twin-3 display” on page 34).
