7.5.2 Additional functions
• Standby sequence
This function inhibits temperature alarm output even if the conditions are met for temperature
alarm output when this product is turned on. Temperature alarm output is generated only when
this product deviates from the conditions for temperature alarm output and satisfies those
conditions again. This function is used for bottom temperature alarm output when this product
is turned on. This function is enabled when this product is turned on in the shaded portion in
the operation table of temperature alarm outputs.
[How to cancel this function]
This function is canceled when this product is activated or when either of the following setting is
changed: target, temperature alarm, PV correction, and temperature alarm setting.
• Temperature alarm output holding
When a temperature alarm output is generated, this function retains that state. Even if this
product deviates from the conditions for temperature alarm output, the temperature alarm output
will remain on.
[How to cancel this function]
To cancel this function, turn this product off and back on or disable the additional function for
temperature alarm output setting.
