H--L

High & low current output limits

Defines the lower ‘Lo’ and upper ‘Hi’
4/20mA Set Point Station output current
limits.
See section 5.6

P5Et

Pre-set outputs

The values of the five pre-set current out-
puts are defined by this function. The
pre-set output currents are identified

5Et1

to

5Et5

and are displayed in engin-

eering units.
This function only appears in the config-
uration menu when

P5Et

, which allows

pre-set values to be viewed and selected
in the operating mode, is selected in the

P

 

.

 

Fn

 function.

See section 5.7

rAtE

Maximum output rate of change

Enables the maximum rate of change of
the 4/20mA output current to be defined.
Adjustable between approximately 1 and
100 seconds for full scale output travel.
0 disables this rate of change limit.
See section 5.8

P

 

.

 

Fn

Function of

(

push button in operat-

ing mode.

The Set Point Station may be configured
to display the output current in milliamps,
the output current as a percentage or to
provide access to the five pre-set outputs
when the

(

push button is pressed in

the operating mode.

EnC

Encoder

In addition to the Set Point Station
4/20mA output being adjusted by the
front panel push buttons, an external
quadrature encoder may be connected to
provide control via a rotary knob.

This

function allows the number of pulses per
revolution of the knob to be entered.
See section 5.10

Hnd

One or two handed operation

Allows the Set Point Station output cur-
rent to be adjusted by the front panel

&

 or 

*

push button and by the optional

external encoder with or without the

)

button be pressed at the same time.
See section 5.11

CodE

Security code

Defines a four digit numeric code that
must be entered to gain access to the
configuration menu.

Default code

0000

disables this security function and allows
unrestricted access to all conditioning
functions.
See section 5.12

r5Et

Reset

Returns the Set Point Station configura-
tion to the default condition. To prevent
accidental use, reset must be confirmed
by entering

5urE

before it will be ex-

ecuted.
See section 5.13
