Thumbwheel Switch Setting Type LCD Display Timer Proper Usage Caution It may cause electric shock if touching the input signal terminal (between start, reset, inhibit and terminal ) when the power is supplied. Power connection Connect AC power line between (-7) for AC power type. But please aware power connection for DC power type. (, 7 ) When turning off power, be sure about inductive voltage, residual voltage between terminal (-7), it may cause problem with low voltage because power consumption is low and impedance is high. (if using power line in with another high voltage line or energy line in the same conduit, it may cause inductive voltage. Therefore please use separate conduit for power line.) Power ripple should be under % and power supply should be within range of allowable voltage for DC power type. Please supply power quickly as using a switch or relay contact, otherwise it may cause timing error. When using SSR (solid state relay) for switching power source of Timer, dielectric strength voltage should be times higher than power source. Input/Output Please check operation mode of this unit before connecting the power. If setting for operation time, output may not work. When using a relay contact as input signal, please use reliable contact enough to flow 5VDC ma of current. (short circuited: Contact resistance under kω, Open circuit: Residual voltage under.5v) In case of connecting terminal () and power terminal () of, do not start time at the same time applying power. Please use relay contact or transistor to start. (time error occurs when time starts the moment power is supplied.) When power is applied to A, B, it starts to operate,please check operation specification before using. (it may cause breakdown of peripheral device when power is applied without any check.) is transformer-less type, therefore please check following for connecting a relay contact, input signal and transistor. When connecting or more than Timers with relay contact for input or transistor, please connect as following <Figure. >.
