==== | ====Description==== | ||
When the controller is turned on, the A4 output may be in the open or semi-open state. | |||
If a power supply is directly connected to the A4 terminal block (the terminal block is used as an input), a short circuit on the power supply line may occur when the controller is switched on, and the output stage of the A4 output may burn. | |||
==== | ====Reasons and detailed description==== | ||
The gate of the transistor at the output of A4 is incorrectly tightened. | |||
==== | ====Workarounds==== | ||
* ( | * (preferred) do not connect PSU to A1-A4 inputs directly, connect via resistor in 1-10kω. With this resistance, the digital and analog inputs will work, but switching on the transistor (A4 or any other) will not burn out the output. | ||
* | * Send the device for warranty repair | ||
==== | ====Scheduled fix=== | ||
Scheduled for correction in devices shipped after 10.2016. |
