h3ca 10 installation terminal arrangement input connections signal inputs connect the start input contact between terminals c and f , the reset input contact between terminals c and g , the gate input contact between terminals c and e , and the check input contact between terminals c and d . for each signal input contact, use a gold-plated contacts with high reliability. be sure that these input signals satisfy the following requirements: a resistance of 1 k ? (max.) and a residual voltage of 1 v (max.) when the contact is made. solid-state signal inputs connect the start input transistor between terminals c and f , the reset input transistor between terminals c and g , the gate input transistor between terminals c and e , and the check input transistor between terminals c and d . for signal input, use an open collector type transistor with characteristics: v ceo = 20 v min., v ce(s) = 1 v max., ic = 50 ma min. and i cbo = 0.5 a max. in addition, be sure that the input signals satisfy the following requirements: a resistance of 1 k ? (max.) and a residual voltage of 1 v (max.) when the transistor is on, and a resistance of 200 k ? (min.) when the transistor is off.

h3ca 11 from a solid-state circui t (proximity sensor, p hotoelectric sensor, or the like) with rated power supply voltage ranging from 6 to 30 vdc, input signals can also be applied by other than an open collector type transistor as shown in the followi ng diagram. the input signal from a solid-state circuit is applied when output transistor tr turns on. in terms of signal voltage, the signal is input when it goes from a high to low level. again, the residual vo ltage should be 1 v (max.) when the transistor is on. as the current output from the timer to tr is approximately 0.1 ma, this connec tion is possible provided the residual voltage is kept to a maximum of 1 v. note: except for the power supply circuitry, avoid the laying of input signal wires in parallel or in the same conduit with high-tension or power lines. it is recommended to use shielded wires or wiring with independent metal conduits for the shortest possible distance. solid-state circuit (proximity sensor, photoelectric sensor, etc.) h3ca-8 (+) (-) (+) (-) h3ca-8h

h3ca 14 safety precautions how to change operation mode operate the pushbuttons of the thumbwheel switch, located at the leftmost position on the front panel to set the operation mode. eight operation modes (a, b, c, d, e, f, g, and h) are selectable and the selected operation mode is displayed in the operation mode display window. how to change time unit and rated time operate the pushbuttons of the rightmost thumbwheel switch to select the desired time unit. seven time units (0.1 s, s, 0.1 m, m, 0.1 h, h, or 10 h) are selectable and the selected time unit is displayed in the time unit display window. the desired rated time is specified by operating the three thumbwheel switches in the middle of the front panel. the range of rated time is 001 to 999 for each unit. time unit and rated time ! caution 1. do not change the time unit, rated time, or operation mode while the timer is in operation. otherwise, the timer may malfunction or be damaged. be sure to turn off the power supply to the timer before changing the timer unit, rated time or operation mode. 2. note that output will be generated in c, d, e, g, or h mode even if the rated time is set to 000. no output will be generated in a, b, or f mode. connecting the operating power supply the h3ca-8 @ contains a capacitor-d rop power circuit. use a sinusoidal power supply with a commercial frequency. do not use power supplies with a high frequenc y component (such as inverter power supplies) for timers with 100 to 240-vac specifications. using these power supplies can damage internal circuits. the power supply connections to the H3CA-A and h3ca-fa can be made without regard to polarity for both ac and dc power supplies; just connect to the specified terminals (2 and 10, or a1 and a2). when connecting a dc power supply to the h3ca-8 or h3ca-8h, however, the polarity must be connected as indicated. although there is a wide range of power connectable to the H3CA-A and h3ca-fa, be sure that there is no inductive voltage or residual voltage applied to the timer power supply terminals (2 and 10, or a1 and a2) when the power switch is turned off. (inductive voltage can be generated in the power supply line if it is placed in parallel with high-voltage or power lines.) a dc power supply can be connected if its ripple factor is 20% or less and the mean voltage is within the rated operating voltage range of the timer. connect the power supply voltage through a relay or switch in such a way that the voltage reaches a fix ed value at once or the timer may not be reset or a timer error could result. h3ca-8 and h3ca-8h timers with ac specifications are equivalent to capacitor loads. when switching the timer power supply with an ssr, use an ssr with a withstand voltage of twice the power supply voltage. since the h3ca-8 and h3ca-8h ti mers of ac specifications externally discharges a part of in ternal energy when the power is turned off, it may malfunction if an extremely sensitive relay is used with the following sequence circuit. if such a malfunction occurs, change the circuit configuration as shown below on the right side. time unit rated time 0.1 s 0.1 to 99.9 s s 1 to 999 s 0.1 m 0.1 to 99.9 m m 1 to 999 m 0.1 h 0.1 to 99.9 h h 1 to 999 h 10 h 10 to 9,990 h note: the operation mode is fixed to "a" for h3ca-8h. the characters are yellow. remaining time display the remaining time is displayed as a decreasing percentage between 0% and 100%. time unit selector time unit display window 0.1 s, s, 0.1 m 0.1 h, h, 10 h rated time selector rated time display window 001 to 999 note: the characters are yellow. t/b x/a t/b x/a x/a if malfunction is expected.
h3ca 15 input/output the operation of the output contacts varies with the operation specifications. before making connections, check the operation specifications and operating co nditions using the application examples provided. the H3CA-A and h3ca-fa do not use transformers. simultaneous inputting power from two or more power supplies to separate timers or counters from a single input c ontact or transistor is not possible. for the power supply of an input de vice, use an isolating transformer, of which the primary and secondary windings are mutually isolated and the secondary winding is not grounded. a transformer is not used in the power supplies for the H3CA-A and h3ca-fa. you can therefore receiv e an electrical shock by touching the input terminals when the power supply voltage is being applied. take adequate precautions to prot ect against electrical shock. inputs to input signal terminals are made by shorting the individual input terminals to the common terminal (terminal 3 for the H3CA-A or terminal (x) for the h3ca-fa). internal circuits may be damaged if connections are made to any other terminals or if voltages are applied. if contacts are used to short the te rminals, they will be switching a low voltage (approximately 5 vdc) and current (approximately 100 a). you must therefore use high -reliability cont acts with a contact resistance of 1 k ? or less when shorted and residual voltage of 1 v maximum when shorted. the reset input will take priority if both the set and reset inputs are turned on simultaneously. others holding relays are used for outputs on the H3CA-A series. dropping the unit or otherwise subjecting it to shock can cause the relay to reverse or to move to the center position. how to mount the timer on mounting track when mounting a h3ca-fa timer on a socket mounting track, observe the following procedures: mounting first hook portion a of the timer to an edge of the track and then depress the timer in direction b. dismounting pull out portion c with a round-blade screwdriver and remove the timer from the mounting track. H3CA-A/-fa input terminal power supply circuit isolation transformer is required. rectifier circuit b a c in the interest of product improvement, specif ications are subject to change without notice. all dimensions shown are in millimeters. to convert millimeters into inches, multiply by 0.03 937. to convert grams into ounces, multiply by 0.03527.
