Additive Feeders Chapter 4: Operation 23 of 50
Timer/Counter Control Operation (Injection Molding Applications)
The Timer/Counter control is designed for use with cyclical processes like injection molding
and features a timer and counter module. It also acts as a cycle override safety timer.
Timer Module
This feature of the controller assists in calibration of the additive feeder (See Page 20 for
specific calibration instructions.).
Procedure
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 automatically stops.
Used as a Cycle Override Safety Timer
This component of the controller allows the operator to override the molding machine shot
cycle when the additive feeder motor is running in AUTO mode.
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.
