Analog output PI control
Display:
rec ctrI
Range:
on
or
OFF
Default Value:
OFF
Analog output mode - seen only when analog output option is fitted. This function allows selection
of
on
or
OFF
for PI control analog output. If set to
OFF
the analog output operates as a
retransmission output and uses the functions described in this chapter. If set to
on
the analog
output operates as a PI control output.
When this function is set to
on
the following associated functions will appear:
C.SEt
,
C.SPN
,
C_PG
,
C_Po
,
C.IG
,
CIL.H
,
CIL.L
and
REC SPAC
. These functions are not detailed in
this manual. Refer to the separate “PM4 Panel Meter Optional Output Addendum” booklet for
description of the analog PI control functions and wiring details.

Rate display decimal point selection
Display:
RAtE dCPt
Range:
0
to number of display digits minus 1
Default Value:
0
Rate decimal point selection - only seen when
FREQ
or
both
mode selected. Displays and sets
the decimal point position for the rate display. For example selecting
0
will mean no decimal
points (e.g. a display such as
25
),
0.1
means 1 decimal point place (e.g.
2.4
),
0.02
gives 2
decimal point places (e.g.
2.35
) etc. The maximum number of decimal point places is one less
than the number of digits on the display e.g. a 4 digit display can have 3 decimal points, a 6 digit
display can have 5 decimal points etc. Note: If the number of decimal points is altered then the
display scaling figure (
RAtESCLE
) will also be affected. Always check the scaling figure following
a decimal point change and alter as required.
7.29
Rate input scale factor
Display:
RAtE INPt
Range:
Any display value
Default Value:
1
Rate input scale factor - only seen when
FREQ
or
both
mode selected. Displays and sets the
number of input pulses to be used with the rate scale function to generate the display scaling. See
examples later in this chapter and formula below.
7.30
Rate scale factor
Display:
RAtE SCLE
Range:
Any display value
Default Value:
1
Rate scale factor - only seen when
FREQ
or
both
mode selected. Displays and sets the scale
factor to be used with the rate input setting. See examples later in this chapter. Scale and input
