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.
PARTS
both ends of VA1
both ends of CM1
both ends of CM2
both ends of CE2
both ends of CC2
VOLTAGE
230Vac
14Vac
17Vdc
12Vdc
5Vdc
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 occurring CLOCK which motivates the internal local element of IC1 to transmit and receive an information and
BASIC TIME for calculating time. Use a proper form for OSC 1. Because in case 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 when the early power ON or apply power again in MICOM
after temporary power failure. As a result, all the functions operate according 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 5V
during the general operation.
