c-68 preset counter/timer h8gn precautions !caution do not use the product in locations subject to flammable or explo- sive gases. doing so may result in explosion. !caution the service life of the output relays depends on the switching ca- pacity and switching conditions. consider the actual application conditions and use the product within the rated load and electrical service life. using the product beyond its service life may result in contact deposition or burning. !caution do not disassemble, repair, or modify the product. doing so may result in electric shock, fire, or malfunction. !caution do not allow metal objects or conductive wires to enter the prod- uct. doing so may result in electric shock, fire, or malfunction. other precautions store at the specified temperature. if the h8gn has been stored at a temperature of less than ? 10 c, allow the h8gn to stand at room temperature for at least 3 hours before use. use the product within the ratings specified for vibration, shock, submerging in water, and exposure to oil. do not use the product in locations subject to dust, corrosive gases, or direct sunlight. use the product within the ratings specified for temperature and humidity. the product is designed for 24 vdc. applying voltages other than the rated one such as 100 to 240 vac may damage the internal elements. separate the input signal devices, input signal cables, and the product from the source of noise or high-tension cables producing noise. separate the product from the source of static electricity when using the product in an environment where a large amount of static electricity is produced (e.g., forming compounds, powders, or fluid materials being transported by pipe). do not expose the product to organic solvent such as thinner or benzine, strong alkali materials, or strong acid materials. doing so may damage the product surface. application precautions 1. do not use the product in locations where condensation may occur due to high humidity or where temperature changes are severe. 2. be sure to wire terminals correctly, with the correct polarity. 3. maintain the power supply voltage within the allowable ranges. 4. connect the power supply through a relay or switch so that the voltage reaches a fixed value immediately. if the voltage increases gradually the power supply may be reset or outputs may turn on. 5. when the power is turned on, an inrush current (approx. 15 a) will flow momentarily. depending on power supply capacities, the product may not start due to this leakage current. the power sup- ply must be of a sufficiently large capacity. 6. for the main power supply or the power supply for input devices, use a power supply transformer whose primary side is insulated from the secondary side and whose secondary side is not grounded. 7. leaving the h8gn with outputs on at a high temperature for a long time may hasten the degradation of internal parts (such as electrolytic capacitors). therefore, use the product in combination with relays and avoid leaving the product as long as more than 1 month with the output turned on. power supplies when turning the power on and off, input signal reception is possi- ble, unstable, or impossible as shown in the diagram below. turn the power on and off using a relay with a rated capacity of 15 a minimum to prevent contact deterioration due to inrush current caused by turning the power on and off. when power is turned on, a starting current flows momentarily. therefore, pay attention to the overcurrent detection level of the power supply used. timer control with power start to allow for the startup time of peripheral devices (sensors, etc.), the h8gn starts timing operation between 210 to 260 ms after power is turned on (see diagram above). for this reason, in operations where timing starts from power on, the time display will actually start from 258 ms. if the set value is 258 ms or less, the time until output turns on will be a fixed value between 210 and 260. (normal operation is possible for set value of 259 ms or more.) in applications where a set value of 258 ms or less is required, use start timing with signal input. when the h8gn is used with power start in f mode (i.e., accumula- tive operation with output on hold), there will be a timer error (approx- imately 100 ms each time the h8gn is turned on) due to the characteristics of the internal circuitry. use the h8gn with signal start if timer accuracy is required. changing the set value in counter operation when changing the set value during operation, the output will turn on if the set value equals the present value. in timer operation when changing the set value during operation, if the set value is changed in so that the conditions below are satisfied, the timer oper- ates in the same way as when the present value reaches the set value because a constant read-in system is in use. depending on the output mode, this may result in output turning on. timer mode up: present value set value timer mode down:elapsed time set value (present value = 0) note: when in down mode, the amount set value is changed is add- ed to or subtracted from the present value. 210 ms 5 ms input impossible unstable possible impossible unstable 0 to 50 ms 0 to 500 ms on off power supply
preset counter/timer h8gn c-69 counters operation with a set value of 0 in counter operation the output will turn on if the set value (0) equals the present value. the output will be off while the reset key is pressed or the reset input is on. in timer operation 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. response delay time when resetting the following table shows the delay from when the reset signal is input until the output is turned off. output delay time the following table shows the delay from when the timer value passes the set value until the output is produced. actual measurements in n or k mode *the variation in delays is due to different modes and conditions. mounting tighten the two mounting screws on the adaptor. tighten them alter- nately, a little at a time, so as to keep them at an equal tightness. the h8gn ? s panel surface is water-resistive (conforming to nema 4x (indoors) and ip66). in order to prevent the internal circuit from water penetration through the space between the counter and oper- ating panel, attach a rubber packing (provided with the h8gn) between the counter and operating panel and secure the rubber packing with the y92f-34 flush-mounting adaptor. output the spdt (single-pole, double-throw) consists of an spst-no con- tact and an spst-nc contact. do not form a circuit with 3-point short-circuit (power short-circuiting with arc). reference for details about communications functions, refer to h8gn preset counter/timer user ? s manual (catalog no. m066). minimum reset signal width output delay time 1 ms 3.7 to 6.0 ms 20 ms 19 to 21 ms control output max. counting speed output delay time* contact output 30 hz 17.3 to 18.9 ms 5 khz 3.5 to 5.2 ms adaptor waterproof packing panel power supply short-circuit current

(setting range: 1 to 99 s.) the time before auto-return of the display can be set here. if this setting is set to off, the auto-return function will not operate. 5. move-to-protect-level time ( prlt ) if the and keys are pressed for more than 3 seconds in the operation level, the display will move to the protect level. use this setting to change the time that the key must be pressed to any time within the setting range (3 to 30 s). protect level 1. operation/adjustment protection ( oapt ) the following table shows the protection given for each setting level. not protected: display and setting changes are possible. display only: display is possible. no display, no level shift: display and level shifts are not possible. the initial setting level is 0 and no protection is given at this set- ting level. 2. initial setting/communications protection ( icpt ) moving to initial setting, communications setting, or advanced function setting levels is restricted. ok: move to other levels possible no: move to other levels not possible the default setting is 1. 3. setting change protection ( wtpt ) restricts setting changes using front panel keys. the default setting is off. 4. reset key protect ( rpt ) prohibits the use of the reset key. the default setting is off.
