h7e @-n@p 24 connections terminal arrangement connections power supply and battery connections battery connections when designing a circuit, keep the power wiring connections shorter than 50 mm. refer to the connection diagram above for the proper wiring polarity. the life expectancy of a battery power supply can be calculated by the following formula: t = a/l c where, t: life expectancy of battery (h) a: battery capacity (mah) l c : h7e @ -n @ p current consumption (ma) example: battery life when using a 3-v lithium battery with a capacity of 1,200 mah for the h7e @ -n @ p. t = 1,200 [mah]/20 10 ?3 [ma] = 60,000 hours (approx. 6.8 years) the battery capacity varies depending on the type of battery used; oxidized silver, mercury, or lithium battery. voltage division of power supply circuit when necessary, the voltage from the battery may be divided by resistances: when doing so, however, ensure that the following equation balances: e (v) r 2 / (r 1 + r 2 ) = 3 v allow a current high enough to flow through r 1 so that the h7e @ - n@ p receives sufficient current. c is a film capacitor, of about 0.1 f, and is intended to absorb noise induced by the power lines. keep the wiring between the h7e @ -n @ p and r 2 or c as short as possible (within 50 mm). backup circuit for protection against power failure use a diode (d) having a forward voltage as small as possible (0.1 v max. at i f of 20 a). determine the ratio of r 1 to r 2 in accordance with the forward volt- age of the diode to be used. be aware that when the power supplied to the h7e @ -n @ p has dropped to less than the voltage of the backup circuit, the battery will discharge. to protect the circuit against a momentary power failure, an aluminum electrolyte capacitor can be used in place of a battery, as shown below: when a capacitor is used, its back up time can be calculated by the following formula: t = c (v 1 ? v 2 ) / i c where, t: backup time (s) c: capacitance ( f) v 1 : supply voltage before power failure (v) v 2 : minimum operating voltage of h7e @ -n @ p (v) i c :h7e @ -n @ p current consumption ( a) example: backup time by an aluminum electrolytic capacitor of 100 f. (mini- mum operating voltage of h7e @ -n @ p is 2.6 v.) t = 100 f (3?2.6 v)/20 a = 100 0.40/20 = 2.0 seconds note that the above calculation provides an approximate value, which varies depending on the environment under which the counter is used and also on the type of capa citors used. provide some allow- ance in selecting capacitors. keep the wiring between the h7e @ -n @ p and r 2 or c as short as possible (within 50 mm).

(with the h7 er-n,-nv(-h),-nv1(-h), models, ?0? or ?0.0? will be displayed after 1 s.) switch settings on the counter must be performed before mounting it to a control panel. do not use the counter in the following locations: locations subject to seve re changes in temperature. locations subject to condensation as the result of high humidity. mounting precautions for flush mounting although the operating section is watertight (conforming to nema4, ip66), rubber packing is provided to avoid water leakage through the gap between the counter and panel cutout. unless this rubber pack- ing is tightly squeezed on, water may permeate inside the panel. therefore, be sure to tighten the screws for fixing the y92f-34 flush mounting bracket. (excessive tight ening may also deform the rubber packing.) screw for the flush mounting bracket reset input and count/timer input the h7e operates using its built-in battery. if the h7e is connected to a device that has +v and out terminals that are connected with a diode as shown in the circuit diagram, the circuit indicated by the arrow 1 or 2 will be formed when the device is turned off. as a result, the h7e may be reset or count by one. it is recommended that such devices not be connected to the h7e. if an excessive voltage is applied to the count/timer input or reset input terminals, the internal elements may be damaged. ensure that the following voltages are not exceeded: pnp/npn universal voltage input model: 30 vdc ac/dc voltage input model: at count/timer input: 240 vac (peak voltage: 338v) 240 vdc at reset input: no voltage can be applied. (no-voltage input) no-voltage input model: no voltage can be applied. avoid wiring close to high-tens ion or large-current lines. do not remove the outer case when voltage is being applied to the power supply terminals or the input terminals. the input for the h7e @ -nfv- @ is a high-impedance circuit and so influence from an induced voltage may result in malfunction. there- fore, when the input signal wiri ng is longer than 10 m (line capaci- tance of 120 pf/m, at room temperature), it is recommended that a cr filter or a bleeder resistor is connected. reset key insulation sheet y92f-34 adapter panel the wider side must face the panel. h7e@-n devices internal circuit count/timer input or reset input

(1) 2. pull the body out of its outer case. (2) 3. lift the battery up by the edge and remove it. (3) when removing the battery, do not come in contact with the dis- play area or any internal parts. 4. wipe the back of the new battery before inserting it. 5. ensure that the + and ? terminals are correctly oriented. 6. after replacing the battery, re-insert the body into its case.

(5) en/iec standards the count or timer input, reset input, and backlight power supply ter- minals of the no-voltage input or pnp/npn universal dc voltage input models (h7e @ -n,-n1, h7e @ -nv(-h),-nv1(-h)) are not iso- lated. a selv power supply conforming to appendix h of iec61010-1 should be used for the count or time r input, reset input and backlight power supply terminals. a selv power supply is a power supply for which the input and output have double or reinforced insulation, and for which the output voltage is 30 vrms with 42.4 v peak or 60 vdc max. (only the h7e @ -nv @ -h has a backlight.) the terminals for count or timer input and reset input for ac/dc multi-voltage input models have basic insulation. connect the reset input terminals to a device that does not have exposed current-carrying parts and has basic insulation for 240 vac. others if the indicator keeps flickering or is off, the internal battery may be close to the end of its service life. in such a case, it is suggested that the battery be replaced. pcb-mounting counter power supply use the power supply within the applicable range indicated by the following waveform, while considering the ripple and voltage fluctu- ations of the circ uit power source. the h7e @ -n @ p changes its mode as shown below depending on the applied supply voltage. battery replacement to prevent unwanted reset when replacing the battery, connect the new battery before disconnecting the old one. otherwise, the voltage supplied to the counter circuit drop s, causing the present count value to reset. when designing the circuit board, providing two extra terminals for battery connection will make the sw itch must simpler. see the sche- matic diagram below: wiring polarity must be carefully observed, in order to prevent per- manent damage to the counters. exercise caution when inserting the counter in the socket, to prevent reversed polarity.
