Addition UP LC24-C type * Counts when the operation signal is ON. * While the reset input is ON, the signal does not change. CAUTIONS <Non-voltage input type> 1. Since the current from the operation signal and reset input terminals [1-3 (flush mounting type), E-H (PC board mounting type)] is small, use relays and switches which have high-reliability contact performance. 2. When input signals are triggered through the transistor's open collector, use a small signal transistor with an ICBO less than 1 A, being sure to trigger them with no voltage across the collector. 3. When connecting the signal input and reset input wires, do not run them parallel to high-voltage or power cables and avoid using the same conduit. Use shielded wires or metallic conduits which are as short as possible. If the floating capacitance of the wires exceeds 500 pF (approx. 10 m for parallel wires of 2 mm2), it will cause malfunctions. 4. Lithium batteries are built in the flush mounting types. Never throw them into a fire. Do not dispose of them in trash intended to be incinerated. *PC board mounting type-- 1. After connecting the external power, be sure to reset it to make sure that "0" appears on the display. 2. Battery life is calculated as follows: t=A I t: Battery life (h) I: Consumption current (mA) A: Battery capacity when the operating voltage becomes minimum. 3. Hand soldering: Soldering iron Iron tip temperature Soldering time 62 30 W to 60 W Approx. 300C (572F) Less than approx. 3 seconds Example IN Reset Count 1 0 9999999 0 1 0 Example IN Reset Count 0 1 <Voltage input type> * AC/DC Voltage input type 1. Apply voltage to the signal input terminal. Do not apply voltage to the reset input terminal. When voltage exceeding the range of the rated input voltage is applied to the signal input terminal, or if voltage is applied to the reset terminal, it may cause break-down of internal elements. 2. Since the current from the reset input terminal is small, use relays and switches which have high-reliability contact performance. 3. When reset is triggered through the transistor's open collector, use a small signal transistor with an ICBO less than 1 A, being sure to trigger it with no voltage across the collector. 4. For external reset, make a temporary short-circuit between the rear reset terminals [3-4]. * DC voltage input type 1.When more than 30 V DC is applied to the signal or reset input terminals, it may cause breakdown of internal elements. 2. For external reset, voltage is applied between the rear reset terminals [3-4] to the H level (4.5 to 30 V DC). In this case, connect (-) to terminal 4 and (+) to terminal 3]. Since they are polarized, they will not operate with reverse polarity. 9999999 0 1 0 * Common 1. When connecting the operation signal wires [1-2] and reset input wires [3-4], do not run them in parallel with high-voltage or power cables. Avoid running signal or reset wires in a power conduit. Use shielded wires or metal conduits which are as short as possible. If the floating capacitance of these wires exceeds 500 pF (approximately 10 m for parallel wires of 2 mm2), it will cause malfunctions. 2. Lithium batteries are built in.
