TP36V - 36V voltage
TPGND - GND
TP1 - 5V digitals
TP2 - Lamp voltage from 11.7 V <12V
TP3 - 12V Analogicals
TP4 - 12V Valves and diaphragm pumps
TP5 - 12V thermostatation
The existing bridge is to enable the different supply voltages. It has the same function as the enable of the J1 connector.
List of LED diodes:
D3 - Indicates 5V activated
D4 - Indicates 12V lamp activated
D7 - Indicates 12V valves activated
D8 - Indicates 12V analogicals activated
D10 - Indicates 12V thermos activated
3.2 Power Supply Board (CIIM00007)
This is made up of 5 different switched voltage regulators that enable distribution of the power supply in accord with the
