2.2 – FEEDBACK SENSOR
The CD30 is setup to operate with the standard DMT & Mag II sensor (Gordon p/n 06A578) as
well as PPM's own accelerometer. It gets wired into the terminal strip on the CD30/35, so the
existing DMT connector on the end of the sensor wire must be cut off if replacing an existing
DMT or Mag II with a CD30/35.
Wiring connections for DMT/Mag II sensor:
• Black (ground) – terminal 1
• Red (+24v) – terminal 3
• White/grey (sensor) – terminal 12
• Black (large wire) (shield) – terminal 16
2.3 – SYSTEM CONTROL WIRING
2.3.1 – ENABLE UNIT
The Unit is enabled by closing contacts or by applying a 24v signal
• Input terminals for contacts: 5 & 6
• Input terminals for 24vdc: 4(-) & 5(+24v)
2.3.2 – EXTERNAL SET POINT (C038~E.S.P.)
NOTE: to enable external set point, set ESP = 1 (on menu C038)
• Potentiometer (10kOhm) input terminals: 7(-), 8(E), 10(+10v)
• 0 to +10vdc input terminals: 7(-), 8(+0 to 10v)
• 0(4) to 20mA input terminals: 7(-), 9(+0 to 20mA)
IMPORTANT – A minimum level for the output voltage can be selected when an external set
point is used (to adapt the set point to give a true minimum vibration of the feeder), this is
achieved by setting the internal set point "A" on the display. This must be done before
switching on the external set point source, through the controller. (Should there be no
requirement for a zero correction then "A" must be set to "0" before the external set point
function is selected).
2.3.3 – STATUS RELAY (C040~r.b.)
Internal relay contact on terminals 14 & 15
Wire into either a 100AC or 24DC relay
• When r.b.=0 (relay closes if output power is present)
• When r.b.=1 (relay closes if incoming (main plant power) power to the controller is
present & there are no error messages displayed)
