e.g. If a holdback value of 10 is set and the program is set to ramp to a setpoint of 600
°C, the program will reach 600 °C, then go into a hold state; the hold indicator will light
until the product temperature reaches 590 °C, the program will then continue to control
again.
The holdback will only apply once per segment, therefore when control has been re-
established, the holdback will not apply again to that segment, even if the product
temperature goes outside the holdback band.
Holdback can only be accessed in supervisor level (level 2) by scrolling with the scroll
until the display shows H.BACK <PROGRAM HOLDBACK>: Use the up and down
keys to select the required Holdback value.
If a multi programmer is used, each program can have its own holdback value assigned
to it.
Note: When a holdback is set, each segment used must have a Ramp Rate assigned
to it, in order for it to be recognised by the program.
