Drawing No. LP1120 Effective 03 2020
connects to a current transformer with an output of 100 mA AC
to ensure that proper heater current is present when the control
output is on, and that little or no current is present when the
output is off. This provides immediate warning of a circuit short
or open, instead of waiting for a high or low temperature
shutdown alarm.
SAFETY SUMMARY
All safety related regulations, local codes and instructions that
appear in this document or on equipment must be observed to
ensure personal safety and to prevent damage to either the
device or equipment connected to it.
Do not use these products to replace proper safety interlocking.
No software-based device (or any other solid-state device) should
ever be designed to be responsible for the maintenance of
personnel safety or consequential equipment not equipped with
safeguards. Red Lion disclaims any responsibility for damages,
either direct or consequential, that result from the use of this
equipment in a manner not specified.
