  • Page 20: Relay Layout (Menu 93)

    Select Menu 93 for relay layout. Each relay may work normally or reversed using the NO/NC field. Most relays should be set to normal. There are twelve/twenty relays inside the AC-2000 SE / AC-2000 PLUS respectively, and there may be additional relay extensions. All the relays are numbered sequentially. Assigning the relay code to each relay causes it to assume the particular function.
  • Page 21 The alarm output, code 40, should be normally closed so that the alarm activates on a power failure. In normally closed mode, the AC-2000 turns the relay on to turn the function off, and releases the relay to turn the function on. Usually, Relay 12 is the alarm relay since it provides both normally open and normally closed contacts.

  • Page 22: Manual Relay Operation

    5.3.1 Manual Relay Operation Any relay with a code of ‘0’ is not part of the automatic system. However, it follows the NO/NC (Normally Open, Normally Closed) specification. To turn it on manually, (for an extended time, as for installing and for troubleshooting) specify code 0, and set NO/NC to 1.

    Radiant heaters used as brooders can have their own dedicated sensors. These do not affect the average temperature reading. If a static pressure sensor is used, it must be connected to one of the analog inputs in place of a humidity sensor. 1.

    6 TROUBLESHOOTING GUIDE Problem: Temperature Sensor does not operate Solution: 1. Replace Temperature sensor or connect it to another terminal. 2. Test the Sensor: Disconnect the two wires of the temperature sensor and measure the resistance. a) For 25° C the resistance should be 30 Kohm. If the temperature is higher, the resistance should be lower (for example at 42°...
  • Page 25 Problem: Relays do not operate Solution: 1. If only one relay is not working, check the related fuse. 2. If a group of 4 or 8 relays are not working, it could be that one of the relay coils shorted causing the thermal fuse (automatic fuse) to short.

  • Page 26: Electrical Grounding

    7 ELECTRICAL GROUNDING CAUTION Always connect temperature and sensor shields to earth ground. Avoid mixing high voltage wiring with sensor and low voltage wiring. Keep the controller as far as possible from heavy contactor boxes and other sources of electrical interference. 7.1 Ground Rods Ground rods are used to efficiently connect the system to earth where current may be dissipated in the soil.
