Operation
Once a set point has picked up, it will not drop out until the pre-programmed
conditions are met. This feature is especially useful to allow the fans to continue
to run until the top oil temperature drops to some lower temperature.
Each output can be controlled directly by a temperature set point. The flexible
programmable logic allows simple configuration to handle more complicated
tasks.
You will need to set pickup and drop out temperatures for each set point you
wish to use. Once set, temperature set points take up to 16 seconds to take
affect. Once you have established the pickup and drop out settings you are ready
to assign the set points to a specific output. A set point will not pickup an output
until you assign it to OUT1, OUT2, OUT3, OUT4, OUT5 OUT6 OUT7, or OUT8.
NOTES:
1. When changing pickup or drop out temperature set points, the new
value takes effect the next time temperature data is updated which
occurs every 16 seconds. However, once a SP is picked up, changing
the pickup temperature to a higher (if over temperature) or lower (if
under temperature) value will not cause the SP to drop out. Once a
temperature set point is picked up, the only way it can drop out is if the
drop out condition is met.
2. SP21, SP22, SP23, and SP24 drop out and pick up are settable in single
probe models, but do not have any function.
