Setting Up Gear-to-Line Operation
The melter can be set up to deliver an adhesive output that is geared to the
production line speed. The gear-to-line capability is enabled or disabled
through the Manual mode key, the motor/pump speed scroll keys are used to
adjust the scaled output, and the actual pump speed is displayed in rpms on
the Pump speed display. When the melter is operating in the gear-to-line
mode, the pump speed follows a 0-10 VDC analog input signal from the
production line.
To connect a gear-to-line input to the melter
1. Route a 2-conductor signal cable from the control equipment to the
melter and through the PG-16 penetration on the back of the electrical
enclosure. Use rigid or flexible conduit or a suitable strain relief to protect
the cable from the sharp edge of the conduit penetration.
NOTE: Use a signal cable suitable for NEC class 1 remote control and
signaling circuits. To reduce the possibility of electrical shorting, route the
cablesothatitdoesnottouchnearbycircuitboards.
SeeFigure3-11.
2. Connect a 0-10 VDC line speed reference signal to terminals A8-X5-1 (+)
and A8-X5-2 (-) on the motor control assembly.
