General

• Operating power

  The M2001 requires 24 or 48vdc power to operate. Set switch #5 for the correct operating voltage and connect the operating power to J1 pair 4. The polarity does not matter. Set option switch #5 before connecting power to J1.

• Power supply

  A 6 watt 24 volt power supply is included with the M2001. If you are using this supply, connect the screw terminals marked 24v- and 24v+ to J1 pair 4.

• Relay output

  The relay has 2 sets of transfer or form "c" contacts. All of the relay contacts are on J2. For simple applications, a single, normally open contact is also available on J1 pair 3. For many applications, all connections may be made with just one cable for power, input, and output.

• Indicators

  2 lamps indicate the status of the M2001. A green idle lamp blinks when the M2001 is on, and no inputs are present. When the M2001 is active, a yellow output lamp will light, while the green lamp stops blinking and remains on.

• Delay/holdover

  The delay/holdover feature allows the M2001 to remain in a continuous active state with ringing, winking, or pulsing inputs. With this feature on, the M2001 remains on until no input is detected for 4.5 seconds. The M2001 will "follow" the input signal when this feature is off.

• Option switches

  A 5 position dip switch controls the functions of the M2001. The switches are numbered from left to right, 1 to 5. When setting a switch, open=off=up, and closed=on=down.

  1. Open to insert a .5uf capacitor for ring detection. Closed for voltage or loop current detection.
  2. Open to insert a 10k ohm resistor for ring or voltage detection. Closed for loop current detection.
  3. Open to detect logic levels lower then vref. Closed to detect logic levels higher then vref.
  4. Open for 4.5sec release delay for voltage detection. Closed for no delay.
  5. Open for 48vdc power operation. Closed for 24vdc power operation.
