2 FUNCTION DESCRIPTION
1) ELECTRIC CIRCUITS
TRANS secondary side is composed of electric power circuits for RELAY driving electricity (12Vdc) and for supplying
electricity to MICOM and IC (5Vdc). The voltage in each part is as follows.
VA1 is the part to protect over voltage and noise. When more than 385V is applied, the thermal-fuse (130°C cut-off, local
option) in a first part of TRANS is cut so that the elements in the secondary side of TRANS are protected.
2) OSCILLATION CIRCUIT
CIRCUIT for CLOCK which motivates the internal local element of IC1 to transmit and receive information and BASIC TIME
for calculating time. Use a proper form for OSC 1. In the event that SPECIFICATION is changed, the calculated time in IC1
is changed or IC1 isn't able to operate.
3) RESET CIRCUIT
All the internal parts of MICOM (IC1) return to the initial condition at power ON in MICOM after temporary power failure.
As a result, all the functions operate acording to the early condition. At the early period of power ON the LOW voltage is
applied in the RESET terminal of MICOM for the fixed time. The RESET terminal is 5 V during the general operation.
