Successively pressing

will scroll through all the parameters of GROUP 1. The last two
parameters of each group allow the default parameters to be restored, and returns to GROUP. If

ESCRIPTION
The keyboard is composed of four push buttons, covered by a silicone protective operator, labeled
▼
,
▲
,
FUNC
and
A/M
.
These keys must be pressed and released to move about in the configure screens. Do not press and
hold a key unless told to do so; simply press the key and release it to advance to the next screen.
The arrow keys
▼
or
▲
may be held down to advance rapidly through the values.
The
▼
is called the “Down Arrow Key”, and is used to decrement or modify the parameter value. In
manual mode it is used to decrement the output value. When pressed for more than 3 seconds in
automatic mode, it used to access and decrease the set point parameter
The
▲
is called the “Up Arrow Key”, and is used to increment or modify the parameter value. In
manual mode it is used to increment the output value. When pressed for more than 3 seconds in
automatic mode, it is used to access and decrease the set point parameter. When pressed for less
than 3 seconds in automatic mode, it used to switch the lower display from set point value,
deviation value, output value (%), output value (RPM) and peak value if enabled.
The
FUNC
(“function”) key is used to access the parameter to view and acts as an “Enter key” when
a value has been modified.
The
A/M
key is used to switch the controller from automatic to manual mode (and back again)
when depressed for more than 1 second. When monitoring / modifying control parameters, it is used
to return to the normal display mode without storing the parameter changes.
Pressing
▼
and
FUNC
together may be used to reset the stored peak value and to reset the alarms.
This function is disabled when the device is controlled by serial link.
Pressing
▼
and A/M together, or the
▲
and A/M may be used to jump to maximum or minimum
parameter values when the instrument is in function mode.
Pressing
▲
and
▼
together, or
FUNC
and
A/M
together, may be used on power-up when the
instrument detects a parameter error; the upper display shows Err and the lower display shows the
parameter name.
If the wrong parameter is a run-time parameter (i.e. from SP to RO.TYP), pressing the
▲
and
▼
push-
buttons will have the instrument load the default parameters for all groups of parameters.
NOTE: All of the actions explained above that require two or more keystrokes must follow the
button pushing sequence exactly.
