POWER
SUPPLY
Power for the relays can come from a user supplied source. 2
Alternative power input points are provided depending upon the power
the user has available.
Connector VAC is used for 15-25VDC or 12-20VAC, 50/60Hz. 500ma.
This input is not sensitive to polarity, either terminal can be used.
If the user has 12VDC to 15VDC, 500ma available then connector marked
12VDc can be used. Be careful with the polarity, using +12 to 12V and
minus voltage to the GND terminal.
Only one power input terminal should be used at one time
OPERATION
During operation the relays will be active at the same time the
Low/OK/High LEDs on the front panel operate and the Zero relay is
activated when the scale is at zero point.
Note the scale must show a small weight before the LOW LED will
activate. See the AE402 User Manual for details of how to set the limits.
User connections to the relays are made using the terminal strips
marked OUT1 to OUT4. The relay active for each LED will depend on the
input connection, Input IN1 controls relay 1, OUT1 for example. But IN1
could be connected to any of the 4 terminals in the AE 402.
CAUTION:
The voltage and current limits of the relay outputs must be less than:
115/230VAC, 1amp or 24VDC. 1amp.
Higher currents may damage the circuit board.
The relays are not specified for higher voltages.
