Fig. 5-8 Switching time diagram: Trigger single dose
The signal indicated at PIN 2 triggers a single dose. The single dose lasts at least 22 seconds. The output signal at PIN 4 in normal operation is High (+20…30 V). The signal will switch to Low (+0 V)
while the lubrication system's motor is actually running. This usually takes between approx. 7 and 17 seconds, depending on the length of the lubrication lines and the viscosity of the lubricant. After
that, the signal switches back to High (+24 V).
