SAFETY NETWORK:

The SH inline heater is protected from accidental damage or unsafe operating conditions with a network of safety interlocks. The safety

interlocks will disengage power to the heaters until power is manually restored at the control. The safety interlocks offered on the SH

inline heater are listed below.

TCO Heater Over-Temperature Fuse:

Any over-temperature situation will cause the main load contactor to disengage, and sound the audible alarm. This will require a manual

reset of the heater once the overheat event has been corrected. The over temperature sensor has a fixed setting of 169°C (336°F).

(Maximum Heater Temperature)

Safety Limit Controller (SLC):

This over-temperature controller is a separate controller mounted inside the control enclosure. It uses a separate temperature sensor to

monitor the hot-zone temperature in the heater.

This over-temperature controller has two different settings:

1. Over-temperature cutoff (SP2). This setting needs to be adjusted manually by the customer, to be set at 135°F (57°C).

This setting will cut off power to the heaters if the internal temperature rises above this value, but will automatically re-

engage the heaters when the temperature drops below this value. This is not an alarm set point.

2. High Limit (HSP1). This high-temperature alarm setting is set at 145°F (63°C). If this temperature is detected at this

sensor. the controller will disengage the main load contactor and sound the audible alarm. This will require a manual

reset of the heater once the overheat event has been corrected.

Heat Sink Thermal Cutoff:

The heat sink for the solid state relays (SSRs) is equipped with a bimetallic temperature switch. If the cooling fan on the heat sink wer to

fail, the temperature of the het sink would gradually rise, resulting in eventual SSR failure. This switch willl cause the main load

contactor to disengage, and sound the audible alarm. This will require a manual reset of the heater once the overheat event has been

corrected. The over temperature sensor has a fixed setting of 176°F (80°C). (Maximum Heat Sink Temperature)
