No cover: With hard cover: N = {48n - 2.5 + (n - 1) x 3} +1/-0 H5CN H5CN Protective Cover The protective cover shields the front panel, particularly the count value setting section from dust, dirt, and water drip, as well as prevents malfunctioning of the timer due to static electricity. Y92A-48D (see note 1) (Soft cover) Note: Y92A-48B (see note 2) (Hard cover) 1. The soft protective cover allows the set value to be set by depressing the thumbwheel switches through it. 2. The hard protective cover prevents the set value from being altered due to accidental contact with the push type thumbwheel switch. It may be, however, difficult to make setting changes of the Timer with the Y92A-48B Protective Cover attached, which must be taken into consideration before using the Y92A-48B Protective Cover. Backup Battery Connection of Battery Leads Y92S-20 With socket P2CF-11 Terminal No. 1 Terminal No. 4 With socket P3G-11 Terminal No. 1 Terminal No. 4 7 H5CN H5CN Installation Connections Power Supply Connection Model Without Backup Power for Memory Protection Connect the timer so that the required supply voltage can be applied across terminals B and G. Solid-state Output Type (H5CN-jNS) With H5CN-jNS, a solid-state output is generated by using an open collector transistor. Connect terminal F (collector) of the timer to the positive terminal of a load and terminal H (emitter) to the negative terminal. When connecting an inductive load to the timer, connect terminal E of the timer to the positive terminal of the loads, since a diode is internally connected between terminals F and E. Model With Backup Power for Memory Protection Connect the timer so that the required supply voltage can be applied across terminals B and J. Model With Backup Power for Memory Protection Contact Output Type (Internal circuit of control output contact) Terminal H, I, and K are for control output contacts. Note: Common terminal A will be internally connected to terminal B if the Counter is a model that operates with DC. Connection of Load Circuit (Control Output) Model With Backup Power for Memory Protection Contact Output Type (H5CN-jN) Terminals E, F, and H are for contact output contacts. Load 1 connected in series with NO contact (between terminals F and H) is normally open, and the load circuit voltage will be applied after the lapse of the set time. The load circuit voltage is normally applied to load B connected in series with NC contact (between terminals E and H), which will be open after the lapse of the set time. (Connection of load circuit) Load 1 connected in series with NO contact (between terminals I and K) is normally open, and the load circuit voltage will be applied to it after the lapse of the set time. The load circuit voltage is normally applied to load B connected in series with NC contact (between terminals H and K), which will be open after the lapse of the set time. Load circuit voltage (250 VAC max.) Note: 8 The maximum load current is 3 A (resistive load). H5CN H5CN Connection of Reset Input Model Without Backup Power for Memory Protection Connection of the reset input contact or an open collector transistor between terminals A and C permits the timer to reset when contact is made or the transistor turns ON. Use of a high-reliability goldplated contact is recommended for the reset input. For the reset input transistor, select the one satisfying the following electrical ratings: VCEO = 20 V min. IC = 50 mA min. ICBO = 0.5 A max. Reset input contact Reset input transistor (Timer resets when contact is made.) (Timer resets when transistor is ON.) Model With Backup Power for Memory Protection Connection of the reset input contact or an open collector transistor between terminals C and G permits the timer to reset when contact is made or the transistor turns ON. Use of a high-reliability goldplated contact is recommended for the reset input. For the reset input transistor, select the one satisfying the following electrical ratings: VCEO = 20 V min. IC = 50 mA min. ICBO = 0.5 A max. Reset input contact Reset input transistor (Timer resets when contact is made.) (Timer resets when transistor is ON.) Model With Backup Power for Memory Protection Connection of the gate input contact or an open collector transistor between terminals C and E permits the timer operation to be interrupted while the contact or transistor is in the ON state. The same recommendations as mentioned above apply on the use of the gate input contact or transistor. Use a gate input contact with a short bounce time because the contact bounce time causes an error in the operate time of the timer for a period equalling the bounce time. Gate input contact (Timer stops when contact is made.) Gate input transistor (Timer stops when transistor is ON.) Simultaneous Input to a Number of H5CN Timers with the Same Contact With one contact, a reset or gate input may be applied to two or more H5CN Timers as shown below. Model Without Backup Power for Memory Protection Connection of Gate Input Model Without Backup Power for Memory Protection Connection of the gate input contact or an open collector transistor between terminals A and C permits the timer to reset when contact is made or the transistor turns ON. Use of a high-reliability goldplated contact is recommended for the gate input. For the reset input transistor, select the one satisfying the following electrical ratings: Model With Backup Power for Memory Protection Gate input contact (Timer stops when contact is made.) Gate input transistor (Timer stops when transistor is ON.) Battery Connection Connect the Y92S-20 backup battery between terminals A and D, paying attention to the polarities. 9 H5CN H5CN Battery Connections When Recording Interruptions Always connect a battery when using Units with a power interruption recording function. Any 3-V battery may be used, but the time the interruption is recorded for will depend on the capacity of the battery. When using the Unit for the first time after purchase, apply power and reset the Unit once before using it. When power is applied for the first time, outputs may be produced, so do not connect the output terminals. If a power interruption continues for 10 minutes or more when a battery is not connected, the display may flash, the count value and displays may be meaningless, and outputs may be produced unpredictably even if the power supply recovers. If this happens, apply power to the reset input before using the Unit further. When connecting the battery using a Socket (P2CF-11 or P3GA-11), check the terminal numbers on the Socket and connect the positive side of the battery to terminal 4 and the negative side to terminal 1. Note: 1. High-speed Repeat Operation Circuit When resetting the timer using the reset input terminal, high-speed resetting is possible at a speed of 0.02 s. Accordingly, by using two H5CN Timers, a high-speed repeat operation circuit can be created. H5CN No. 1 H5CN No. 2 2. Integrating Operation Use of the gate input terminal permits the timer to sum up timers T1, T2, and T3 (i.e., integrating operation) as shown below. UP Display Timer DOWN Display Timer Operating Time Measurement The UP display timers with digital display can be used to measure the operating time of other timers or equipment. (For this measurement, set the set time to the maximum.) Note: 10 The digital display of H5CN stops incrementing when the predetermined operating time of timer "T" has elapsed. H5CN H5CN Alarm Output Circuit The illustration shows an example of alarm output circuit. In this circuit, H5CN outputs an alarm when the time control by the other timer is not completed within the set time of the former. Precautions Undesirable Setting Setting of Operating Time Time Setting Range Setting range (Possible operating time) Rated time 0.001 to 9.999 s H5CN-jZj 0.001 to 99.99 s H5CN-jAj 0.1 to 999.9 s H5CN-jBj 1 s to 99 min 59 s H5CN-jCj 1 min to 99 hrs 59 min H5CN-jDj 1. Since the H5CN Timer is capable of reading the input data at any time during normal operation, the set time can be changed during power application. This feature sets back the output from the timer by temporarily setting the longer time or quickens the output by setting the shorter time. During normal operation, the set time may be accidentally changed by touching a thumbwheel switch. To prevent this possibility, use the optional protective cover Y92A-48B. 2. When the set time is all zeroes (e.g., 000.0 s or 00 hrs 00 min), there will be a momentary control output upon power application which can be used to check normal output. When changing the set time during normal operation, pay special attention not to alter the set value to this state. 3. When changing the set time while power is being supplied, an inadequate push of the thumbwheel switches will display two numbers in one digital display window, causing the operating time to drift widely. Therefore, press the thumb-wheel switches surely. Take particular care in the case when the other three digits are all zero, since the improper setting of the fourth switch to create four zeroes will cause a momentary output. 5 min 30 s 00 hrs 00 min (Momentary output) 4. Take particular care with the H5CN-jZjj, which is capable of setting in 1/1000th of a second, since its digital display may display an error of plus or minus 1/1000 s from the set value. Battery Connection Even if the unit is not provided with a backup battery, the count value will be retained for a minimum of 10 min. If a backup battery is connected, the count value will be retained for approx. 5 years. Replace the backup battery as quickly as possible within 10 min. 11 H5CN H5CN ALL DIMENSIONS SHOWN ARE IN MILLIMETERS. To convert millimeters into inches, multiply by 0.03937.
