;If one or two of a heater's three meters indicates a low reading, a burned-out heater is likely, and should be serviced.

4-3 PLC Control

These dryers are equipped with an Omron C28K programmable logic controller (PLC). The "brick" type PLC has 28 I/O points - 16 inputs and 12 outputs.

All inputs are 115 VAC, except for the 24 VDC input #1 from the dewpoint circuit board. All programming and logic is factory installed on an EPROM, and cannot be modified. A battery backup retains the programming during power failures.

Battery life is 5 years at room temperature.

If the alarm indicator blinks intermittently, replace the battery [P/N A0544701] within one week.

4-4 Process Air Temperature Controller

Standard ACS dryers use a microprocessor based PID control for maintaining process air temperature. The controller is a modular, self-contained unit that can slide from its mounting housing. All parameters except for the process air setpoint are factory set and adjusted; no field adjustment to the internal controls is normally necessary.
