Additive Feeders Chapter 4: Operation 23 of 55
Procedure
1. Time the duration of feeder operation during a typical Injection molding machine
shot cycle.
2. Set the timer to a slightly longer value.
3. Start the additive feeder by flipping the motor switch to the AUTO position.
4. If the timer times out because of a process flow problem, the feeder will
automatically stop.
5. Reset the power switch.
Counter Module
The counter module may be used as an inventory management aid and can also confirm the
total cycles between reset independent of the IMM’s control. Every IMM cycle will
increment the display value. The counter module has battery-backed memory and will not
lose count if the electrical power is interrupted.
• Press the RESET button to reset the counter.
Note: Remove the jumper on the back of the module to lock out the reset
button. Replace the jumper to restore reset button operation.
Disconnect the power before moving the jumper.
Timer/Elapsed Timer Control (Extrusion & Blow Molding Applications)
The Timer/Elapsed Timer control is designed for use with continuous processes like
extrusion and blow molding and features a timer and elapsed time module.
Timer Module
This feature of the controller assists in calibration of the additive feeder (See Page 19 for
specific calibration instructions).
1. Set the timer to the desired calibration period, using the round timer keys (see the
timer information sheet for additional information).
2. Start the additive feeder by flipping the motor switch to the MANUAL position.
3. When the timer times out, the feeder will automatically stop.
Elapsed Time Module
The elapsed time module may be used as an inventory management aid for continuous
processing operations.
The timer module measures the time the additive feeder control receives the monitored
control relay signal from the extruder/blow molder machine. The timer module has a battery-
backed memory and will not lose the elapsed time of operation if the electrical power is
interrupted.
• Press the RESET button to reset the counter.
Note: Remove the jumper on the back of the module to lock out the reset
button. Replace the jumper to restore reset button operation.
Disconnect power before moving the jumper.
