US gas unit power board
US gas ovens is equipped with power board PE2022A0. This board integrates the functionality of the gas
system. Its main functions are:
■ Control the 230 V AC loads of the oven such as motors, contactors, braking elements, solenoid valve,
chemical pump, cooling fan, DRY.Maxi solenoid valve;
■ Read the values measured by the oven sensors such as door switch, core probe, temperature probes,
motor revolution sensor, etc.;
■ Control the flame control boards BRAHMA TGRD81;
■ Control up to two blowers for the air-gas mixture;
■ Feed the 12 V DC loads of the oven such as control panel, LED bar light, etc.;
■ Communicate in CANBUS mode with the control board and accessory boards such as gas fumes
board, internet connection board and sous-vide board;
■ Communicate in MODBUS mode with UNOX complementary accessories such as proofer, hood,
holding cabinet and static oven;
