OPTIONAL
FEATURES
• Fail safe operation of the heater contactor. The contactor will not automatically re-
energize after a power failure, or an alarm condition that shuts down the heater.
• Programmable Logic Controller for operating and alarm logic control.
The following standard options are available:
Automatic Temperature Control Option
The automatic temperature control option allows the power level to be adjusted based
on an entered temperature setting for the process. The temperature controller uses PID
type control and is pre-wired for a ‘K’ type thermocouple (option code TCT) or a
4/20mA pyrometer signal (option code TCP).
Voltmeter Option
The true RMS load voltage is displayed with a digital meter. A true RMS voltage
transmitter is provided for isolation and operator safety.
Lamp-out Detection Option
The lamp out detection option is designed to detect a lamp failure or load loss when
using multiple infrared heaters or zones of lamps in a single heater. The SCR fault /
Lamp out indicator flashes during this condition.
Product Detect “PD” Option
The product detect option automatically adjusts the heater or lamp intensity between
run and idle states when a product is detected on the conveyor. A single turn idle
potentiometer is provided on the front panel. Idling the process saves energy and
equipment wear.
