Sterling 350-2100 CFM Temperature Controller Autotune Procedure, To Auto-Tune the Control

Page 29

The low temperature alarm value is a deviation of the process air temperature set point. The alarm value will track the set temperature. If the low temperature alarm is set to "-25", a low temperature alarm occurs if the process air temperature falls more than 25°F below the process air temperature setpoint.

4.Press until the Level 0 values [process air temperature setpoint and process air temperature] are displayed. The High Temperature Alarm is now set.

5-6 Temperature Controller Autotune Procedure

Auto-tune fine tunes the control's PID to process requirements. Auto-tune whenever the process under control changes or when the controller cycles more than 2° or 3° above or below the setpoint.

Don't be alarmed by the control's response. It may take the process temperature above and below the set points as many as three times. It will then level off and control to the process set point. Auto-tuning can take up to 30 minutes, and is best done before any process is being run.

To Auto-Tune the Control:

1.Press and hold downfor several seconds until the "AT" indicator flashes. The AT LED flashes to indicate that the control is tuning itself.

2.When the AT LED light stops flashing, the controller is tuned and ready for operation.

5-7 Temperature Controller Internal Switches

The control is set up and tested at the factory for optimum operation, and the internal switches don't need to be adjusted. If the control does not work properly, or you suspect someone has accidentally changed some settings, there are two solutions. First, try the AUTO-TUNE PROCEDURE as described in Section 6-11. If that doesn't work, see Section 6-15.

5-8 Temperature Controller Anti-Tamper Lockout Switch

This slide switch prevents unauthorized changes to set points. If this switch [SW101] is On,

the , , and keys are disabled. Only the process set point and alarm settings may be viewed. Dryers are factory-set with the protection turned Off.

Enabling the Lockout Feature:

1.Disconnect main electrical power to the dryer.

2.Press up the latch at the bottom of the control module's front panel and slide out the control chassis.

3.Locate the slide-type switch SW101 {PROTECT} on the left circuit board. Slide it to ON.

4.Slide the chassis back into the control module's housing.

Tamper protection will now be enabled.
