  • Page 13: ４－４．Caution In The System Engineering

    ４－４．Caution in the system engineering CAUTION Unstable power and noise may cause error of performance and alarm. For the system to use this unit, it is required to make design based on this manual descriptions. （１）Stable power used While the system gets stable at power failure, the external output and alarm contact may be on and the care for it must be taken.
  • Page 14 －How to think alarm contacts against inductive load－ The spec for alarm contact of EC-592 is described by the conditions of resistive load. When use the inductive load for alarm contacts, the very high reverse electromotive voltage may be generated and the following trouble tends to be produced.
  • Page 15 CAUTION ・The inductive load shall not be used in principle (Do not use fluorescent lamp). ・When use the inductive load, make the contact amplification outside, but the outside relay coil belong, use the relay driven by the low voltage (within AC100V) and it is protected by an appropriate surge killer.
