TROUBLESHOOTING For further technical assistance, contact technical support at the appropriate company numbers listed. RESET OPTIONS Connecting a wire from the .RST. EN.. (Reset Enable) Input terminal to Common will enable the front panel Reset button. When Remote Reset is required, a wire is connected from the .REM. RST.. input terminal to Common. Pulling this input low causes the counter to reset. The .REM. RST.. can be pulled low by either a mechanical switch or solid-state transistor switch. Switch load and leakage are the same as for .L.S. CNT.. Input above. Note: The RC protection circuit on the .REM. RST.. Input causes a delay of approximately 15 msec in Reset response. BACKLIGHT OPTION Optional backlight versions of the CUB4 require an external 9-28 VDC power supply. The external supply is connected between the V+ and Common terminals as shown in the drawing. Red Lion Controls optional power supply (MLPS1000) is designed to be attached directly to the rear of a CUB4 and is powered from a 85 to 250 VAC source. The MLPS provides power for unit backlighting and a sensor. WARNING: When connecting the wiring for a backlit CUB4L8W measuring an AC input voltage, the neutral of the single phase AC signal is connected to Terminal 1 (COM), and line (hot) is connected to Terminal 5 (LS). The DC supply for the backlighting is connected as shown in the drawing. Three phase AC applications require an isolation transformer. The .H.S. CNT.. Input allows the CUB Counter to operate at speeds up to 5 KHz when driven by bi-polar outputs or external circuits having an output impedance of 3.3 KÙ or less. Input drive voltage must be limited to 3 V maximum to avoid damage to the counter. CMOS and TTL logic outputs can be loaded with a resistor (Rl) to limit drive voltage, or a voltage divider can be used as shown for the PNP O.C. transistor output.
