Operating in Gear-To-Line Mode
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 pump mode key, the pump speed arrow 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 the 0-10 VDC signal from the production line. To set
up the melter for gear-to-line operation, refer to Setting Up Gear-to-Line
Operation in Section 3, Installation.
1. Press the Pump mode key until the LED is turned off.
2. Press the Pump enable key until the LED is turned on.
3. Press the Pump enable key to enable the pump. If needed, use the
Pump speed arrow keys to adjust the scaled adhesive output.
The pump speed display indicates the actual pump speed in rpms.
S If the system has not reached the system-ready state at the time that
thepumpenablekeyispressed,theLEDonthepumpenablekeywill
turn yellow, indicating that the pump is enabled, but not started. The
pump will start automatically when the system-ready state is reached
and when the production line starts.
S If the system has reached the system-ready state at the time that the
pump enable key is pressed, the pump will start and the LED on the
pump enable key will turn green, indicating that the pump is running.
S When the reservoir is empty, the motor will stop after it has rotated
the number of revolutions specified in the dLy (delay after empty)
motor control parameter. To run the pump after it has been turned off
by the control system, press the Pump enable key. The motor will
run for the number of revolutions specified and then stop again.
NOTE: You can change the way the pump enable key operates by
changing parameter 8 (automatic pump on). Refer to Appendix B,
Operating Parameters.
NOTE: When the melter is operating in the gear-to-line mode, the pump
speed is determined by the following equation. Refer to Section 8,
Technical Data, for pump displacement values.
