4.2. Leds Description
4.2.1. Dynamic Braking Unit – GROUP 1
4.2.2. Dynamic Braking Unit – GROUP 2
LED DESCRIPTION
When the heat sink is overheated and the
level exceeds its set limit, overheat
protection is activated and this led is turned
on after the signal is shut off.
OHT
(Red)
It is turned on when the braking unit receives
power supply, because usually it is
connected to the drive.
POWER
(Red)
It is blinking while dynamic braking unit is
