8. H8GN NOTICE 1 Do not use the H8GN in the following locations e Locations with high humidity that may result in condensation e Locations with radical temperature changes 2 Pay the utmost attention not to make mistakes in polarity when wiring the Timer 3 Always maintain the power supply voltage within the specifications 4 Connect the power supply voltage through a relay or switch in such a way that the voltage reaches a fixed value at once Otherwise the H8GN may not be reset or outputs may turn ON 5 Besure that the capacity of the power supply is large enough otherwise the H8GN may not start due to inrush current Approx 15A that may flow for an instant when the H8GN is turned on 6 For the power supply of an input device for the H8GN usean isolating transformer with the primary and secondary windings mutually isolated and the secondary winding not grounded 7 Leaving theH8GN with outputs ON at a high temperature for along time may hasten the degradation of internal parts such as electrolytic capacitors For this reason by using in combination with relays avoid situations where outputs are left ON for a long time e g one month or more 8 If the watertight rubber packing is not compressed sufficiently water may penetrate the panel For this reason be sure to tighten the reinforcement screws of the Mounting Adapter Y 92F 34 Sun 9 The output contacts are SPST NO and SPST NC For this reason
9. be sure not to use these contacts in circuits that will result in 3 point short circuits power supply short circuiting due to arcing 10 In counter operation e Changing the set value When changing the set value during operation the output will turn ON if the set value equals the present value e Operation with set value and present value of O The output will turn ON if the set value of O equals the present value The output will be OFF while the Reset Key is pressed or the reset input is ON 11 In timer operation e Changing the set value When changing the set value during operation the H8GN operates in the same way as when the present value reached theset value because a constant read in system isin use And output may turn ON depending on the output mode if the set value is changed as follows Input mode UP Present value Set value Input mode DOWN Elapsed time Set value Present value 0 Note When in DOWN mode the amount set value is changed is added to or subtracted from the present value e Operation with set value of O a When the output mode is set to A B one shot output D or F output will turn ON when the start signal is input b When the output mode is set to B hold output E or Z output will remain OFF even when the start signal is input VI 12 To allow for the startup time of peripheral devices sensors etc the H8GN starts timing operation between 210 to 260 ms after power
