2.2 Main Control Panel
The central control panel includes the following features:
• Two 1/8 DIN digital temperature controllers. One controller controls the burner(s) and
the temperature in the process chamber. The other controller controls the burner(s) and
the temperature in the oxidizer chamber via a High/Low fire - modulating actuator.
• A 1/16 DIN controller, which serves as an OTS High Temp controller.
• System-on and burner-on indicating lights.
• Relays and interconnects.
• ETC-S High Temperature. All ovens have a second 1/16 DIN digital temperature
controller. This Factory Mutual (FM) approved controller and is used for system lockout
if the temperature exceeds safety limits. This controller is also used in FM and Industrial
Risk Insurers (IRI) approved ovens.
A brief description of the functionality of each of these elements is presented in the
following sections.
