Digital output signals can drive devices such as relays or indicator lamps. 5 to 24 VDC power must be
supplied from an external source. Each output has a maximum current capability of 500 mA. Maximum
voltage capability of these circuits is 40 VDC (see Section 12, Specifications, for more information).
Figure 4b – Sample Digital Output Connections, (power can be in the range of 5 – 24 VDC)
5.4 Check Wiring and Close Access Cover
Double-check all of your electrical connections. Pay attention to polarity of all inputs and outputs – both
low and high voltage. Additionally, insure that all terminals are clamping onto the bare conductor, not on
its insulation. Ensure that wires will not be trapped or pinched when front cover is replaced and secured.
Ensure that excess insulation is not removed from the wires, as this can lead to poor connections or faulty
operation.
Replace the main access cover and secure the 2 screws.
5.5 Confirm Correct Incoming Power
W ITHOUT PRIOR OPERATING KNOWLEDGE , IT IS IMPOSSIBLE TO TELL IF THE PUMP MOTOR WILL
RUN WHEN POWER IS APPLIED TO THE MPC VECTOR. Y OU ARE RESPONSIBLE FOR TAKING THE
NECESSARY STEPS TO ENSURE THAT ALL ASPECTS OF SAFETY HAVE BEEN CONSIDERED ( E . G .,
ELECTRICAL , HYDRAULIC , ETC .).
Turn on power at the mains or distribution panel. If the MPC VECTOR's incoming power is connected
correctly, the backlighting on the MPC VECTOR’s display will illuminate (depending on lighting
conditions, it may be necessary to shade the display to confirm illumination). If the display is not
illuminated, first check the line voltage with a voltmeter. If the voltage is not correct, return to Section
5.3.2 – Power Wiring Information. Otherwise, proceed with the next step.
