CAUTION
Equipment damage
The heater insulator prevents current leakage between the band heater and
the sensor holder. Failure to properly install the insulator may cause the
device to trip a ground fault interrupt circuit.
5. Wrap heater insulator around sensor holder. Make sure the insulator joint
lines up with the band gap of the COe band heater.
6. Slide the COe band heater (Figure 10-18) up onto sensor holder.
Do not tighten the band heater at this time. The heater must rotate freely
around the sensor holder.
7. Check for proper height of COe heater thermocouple (Figure 10-17). Thread
bayonet connector up or down to adjust height.
8. Install and fasten thermocouple (Figure 10-18).
9. Position band heater as shown in Figure 10-20 and Figure 10-21 and tighten
band heater clamp screw.
The heater insulator end joint must line up with the band gap of the COe
band heater.
10. Reconnect the COe sensor, thermocouple, and heater wires at the sensor
housing terminal blocks.
Refer to Figure 10-22.
