- Page 21 Functions 3-11 Output Mode A-1: Signal ON-Delay 2 (Timer resets when power comes ON.) Power Timing starts when the start signal goes ON, and is reset when the start signal goes OFF. While the start signal is ON, the timer starts when the Start signal power comes ON or when the reset input goes OFF.

- Page 32 Chapter Precautions Do not use the product in locations subject to flammable ATTENTION or explosive gases. Doing so may result in explosion. The service life of the output relays depends on the ATTENTION switching capacity and switching conditions. Consider the actual application conditions and use the product within the rated load and electrical service life.
- Page 33 Precautions For the power supply of an input device of the 700-HX, use an isolating Power Supplies transformer with the primary and secondary windings mutually isolated and the secondary winding not grounded. 700-HX H5CX Input Input terminal Power supply terminals Circuit Isolation transformer is required.
- Page 34 When the 700-HX is used with power start in F mode (i.e., accumulative operation with output on hold), there will be a timer error (approximately 100 ms each time the 700-HX is turned ON) due to the characteristics of the internal circuitry. Use the 700-HX with signal start if timer accuracy is required.
- Page 35 Precautions It is impossible to provide two independent power switches as shown below regardless of whether or not the timers are different in phase. Input Power Supply Terminal Input Terminal The following displays will appear if an error occurs. Self-diagnostic Function Confirm the error type using the display, and take the appropriate countermeasures.
- Page 36 Tighten the two mounting screws on the Adaptor. Tighten them alternately, a little at a time, so as to keep them at an equal tightness. The 700-HX panel surface is water-resistant (conforming to NEMA 4 and IP66). In order to prevent the internal circuit from water penetration through...
- Page 37 • Store at the specified temperature. If the 700-HX has been stored at a temperature of less than –10°C, allow the 700-HX to stand at room temperature for at least 3 hours before use. • Leaving the 700-HX with outputs ON at a high temperature for a long time may hasten the degradation of internal parts (such as electrolytic capacitors).
