Table 5.5 Engineering Level
The engineering level can be entered at any time by
pressing the keys. This level contains six
parameters for control configuration and options. The
parameters are defined as:
Manual Mode (hand control) – This feature is used if
the sensor fails. The control can now be used as an
on-off proportional timer to control the load until a new
sensor can be installed. The setting for heating or cool-
ing is 0 - 100% of the proportional cycle time.
Peak Process Values – The minimum and maximum
peak values of the process are indicated here.
Calibrate A-D Converter – This parameter is used
during the calibration procedure.
Fail Safe – This defines the status of the outputs if the
sensor fails.
Lock Parameters – Levels 0, 1 or 2 in the operators
level can be locked-out to prevent unauthorized
tampering.
Configuration Level – This feature allows parameters
to change levels (0, 1 or 2) in the operators level. The
purpose of this is to allow only selected parameters to
be adjustable and all the others to be locked-out. For
example, if only the set point is to remain un-locked, all
the other parameters in level 0 can be moved to level 1.
Then lock out level 1 and 2.
