The H5CX’s panel surface is water-resistive (conforming toIP66) and so even if drops of water penetrate the gaps between the keys, there will be no adverse effect on internalcircuits. If, however, there is a possibility of oil being presenton the operator’s hands, use the Soft Cover. The Soft Coverensures protection equivalent to IP54F against oil. Do not,however, use the H5CX in locations where it would come indirect contact with oil.Waterproof Packing(provided with H5CX-BWSD)Y92S-29Note: Use Waterproof Packing to provide a level of water protectionthat complies with NEMA4, UL Type 4X, or IP66 standards. Order the Waterproof Packing separately if it is lost or damaged.Depending on the operating environment, the WaterproofPacking may deteriorate, contract, or harden and so regular replacement is recommended.2-stage Digital Timer H5CX-B43Operating Procedures■ Setting Set ValuesSet values can be set either as offset values (forecast value setting)or absolute values.
Set values are factory-set to forecast value setting.Forecast Value SettingExample: F-1 ModePresent valueTurn ON the power whilepressing theKey and4 Key.Set valueTiming stoppedTiming possibleForecastset valueForecast value0Change the setting methodusingKeys 1 to 6.Setting MethodSelection ModeForecast output (OUT1)Control output (OUT 2)(Forecast value setting) (Absolute value setting)Turn ON the power again.Run Mode1.
Move to Setting Method Selection Mode by turning ON the powerwhile pressing both theKey and4 Key at the same time.2. Select forecast value setting () or absolute value setting() using theKeys.3. When the power is turned ON again, the Timer will start with theselected setting method.Note 1: In Setting Method Selection Mode, outputs are OFF and thetimer is stopped.2: When the setting method is changed, the set values andpresent value are reset to 0, and outputs are OFF.• OUT1 (forecast output) turns ON when the present value reachesthe forecast value.The forecast value = set value - forecast set valueThe forecast set value is used to set the deviation for the set value.• OUT2 (control output) turns ON when the present value reachesthe set value.• If the forecast set value ³ set value, OUT1 (forecast output) will turnON as soon as timing starts.Absolute Value SettingExample: F-1 ModePresent valueSet value 2Set value 10Control output 1 (OUT1)Control output 2 (OUT 2)• OUT1 (control output 1) turns ON when the present value reachesset value 1.• OUT2 (control output 2) turns ON when the present value reachesset value 2.442-stage Digital TimerH5CX-B■ DIP Switch SettingsAll functions are set using the DIP switch.Item1OFFONTime rangeRefer to the table on the right.3Output modeF-1 modeA mode4Input signal width20 ms1 ms5NPN/PNP inputmodeNPNPNP6Reset Key protectionDisabledEnabled7Up Key protectionDisabledEnabled8Mode Key protectionDisabledEnabledPin 12Pin 2Time rangeOFFOFFONOFF0.01 s to 9999.99 sOFFON0 h 00 min 01 s to 99 h 59 min 59 sONON0.1 min to 99999.9 min0.1 h to 99999.9 h12345678ONOFF(Default setting)Note 1: All the pins are factory-set to OFF.2: DIP switch settings are effective when the power is turnedON again.

Tightenthe terminal screws securely. The recommended tightening torqueis 0.5 N·m.• Leaving the H5CX with outputs ON at a high temperature for a longtime may hasten the degradation of internal parts (such aselectrolytic capacitors). Therefore, use the product in combinationwith relays and avoid leaving the product as long as more than 1month with the output turned ON.There may occasionally be a risk of explosion. Do not use theproduct where flammable or combustion gases are present.This may occasionally cause electric shock, fire or malfunction.Never disassemble, repair or modify the product.This may occasionally cause electric shock, fire or malfunction.Do not allow metal fragments or lead wire scraps to fall inside thisproduct.X2/bTT/aX1/aX1X2• Do not use in locations affected by excessive vibration or shock, orin locations subject to exposure to water or oil.• Do not use the product in locations subject to dust, corrosivegases, or direct sunlight.• Separate the input signal devices, input signal cables, and theproduct from the source of noise or high-tension cables producingnoise.• Separate the product from the source of static electricity whenusing the product in an environment where a large amount of staticelectricity is produced (e.g., forming compounds, powders, or fluidmaterials being transported by pipe).• Organic solvents (such as paint thinner), as well as very acidic orbasic solutions might damage the outer casing of the H5CX.• Use the product within the ratings specified for temperature andhumidity.• Do not use the product in locations where condensation may occurdue to high humidity or where temperature changes are severe.• Store at the specified temperature.
If the H5CX has been stored ata temperature of less than –10°C, allow the H5CX to stand at roomtemperature for at least 3 hours before use.Auxiliary relay(e.g., MY Relay)Sensor■ Precautions for Safe UseOperating and Storage ConditionsX• When the product is operated with no-voltage input (NPN input),approximately 14 V is output from the input terminals, so connect adiode if the external power supply is less than 14 V.If both the power supply for the input device and that for the timerare not insulated, unwanted current from the AC power supplymay occasionally burn out or damage the internal parts.
Alwaysuse an insulated power supply for the timer.The following precautions must be observed to ensure safety.X1/a0VInput• Install a switch or circuit-breaker that allows the operator toimmediately turn OFF the power, and make sure it is labeledclearly.• The H5CX’s panel surface is water-resistive (conforming to NEMA4, UL Type 4X, and IP66). In order to prevent the internal circuitfrom water penetration through the space between the H5CX andoperating panel, attach a waterproof packing (Y92S-29) betweenthe H5CX and installation panel and secure the waterproof packingwith the Y92F-30 Flush-mounting Adapter.0.5 to 1 mmIt is recommended that the space betweenthe screw head and the adapter should be0.5 to 1 mm.• Tighten the two mounting screws on the Adapter. Tighten themalternately, a little at a time, so as to keep them at an equaltightness.
If the panel screws are tightened unequally, water mayingress inside the panel.Usage Precautions• Make sure that the voltage applied is within the specified range,otherwise the internal elements of the counter may be damaged.• The load current must be within the rated current.• Ensure that the power is turned OFF before changing DIP switchsettings. Changing DIP switch settings with the power turned ONmay result in electric shock due to contact with terminals subject tohigh voltages.• Pay attention to terminal polarity to ensure correct wiring.• Make sure that the fluctuation of the supply voltage is within thepermissible range.• Apply the power supply voltage through a relay or switch in such away that the voltage reaches the rated value within 2 s.
If thevoltage is applied gradually, the power may not be reset or unstableoutput operations may result.Digital Timer H5CX47■ Precautions for Correct UsePower SuppliesTurn the power ON and OFF using a relay with a rated capacity of 10A minimum to prevent contact deterioration due to inrush currentcaused by turning the power ON and OFF.Be sure that the capacity of the power supply is large enough,otherwise the Timer may not start due to inrush current that may flowfor an instant when the Timer is turned on.When turning the power ON and OFF, input signal reception ispossible, unstable, or impossible as shown in the diagram below.PowersupplyONOFF200 ms 0 to 50 ms5 ms0 to 500 msResponse Delay Time When Resetting(Transistor Output)The following table shows the delay from when the reset signal isinput until the output is turned OFF.(Reference value)Minimum reset signal width0.8 to 1.2 ms20 ms15 to 25 msPower Failure BackupAll data is stored in the EEPROM when there is a power failure.
