Sterling 882.00274.00 Timer Module, Used as a Cycle Override Safety Timer, Counter Module

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.
