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/gear‐to‐line switch, the motor (pump) speed dial is 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.
If you want to use the gear‐to‐line capability, you will need to supply a
line‐speed signal to the melter in one of the following ways:
Use a (customer‐supplied) line‐speed signal generator to measure
the speed of the production line.
Use an analog signal from the production line automation.
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 floor of the electrical
compartment. 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 class1 remote control and
signaling circuits. To reduce the possibility of electrical shorting, route the
cable so that it does not touch nearby circuit boards.
2. See Figure3‐8. Connect a 0-10 VDC line speed reference signal to
terminals TB2‐1 (+) and TB2‐2 (-) on the motor control board.
3. If the maximum value of your line‐speed signal generator is less than
10VDC, change the value of parameter tFr (maximum output frequency).
Refer to
To change motor drive parameter tFr (if needed) after this
procedure. Return here to continue.
4. If you want to run the motor at a minimum speed other than rpm equals 0
at 0VDC, change the value of motor control parameter LoS (minimum
pump speed in gear‐to‐line mode). Refer to
Setting Up the Motor Control
earlier in this section.
