input terminals open circuit and another set with the remote input terminals short circuit to
ground. The remote input can then be used to switch between one set and the other. This
allows two different load cells to be connected with a remote input being used to select the
correct scaling for each or the same load cell could be used and the remote input used to
toggle between different display units. Note: Alarm settings will not change when changing
between calibrations scales. Only one set of alarm functions can be made and the alarm
relay will operate from those set values no matter which calibration scale is being viewed at
the time. The
dCPt
,
Lo dISP
,
HIGH dISP
,
dISP
, and
ZERO RNGE
functions can be
individually set for each channel. If
P.SEt
is used only one preset value can be used but only
the channel displayed at the time is affected. Note; using different
dCPt
settings between
channels will affect the preset and alarm setpoint values e.g. a preset of
25
on a channel
with
dCPt
=
0
will become
2.5
on a channel with
dCPt
=
0.1
.
duLL
- display brightness control. The remote input can be used to change the display brightness.
When this mode is selected the display brightness can be switched, via the remote input
terminals, between the brightness level set at the
brGt
function and the brightness level set
at the
duLL
function.
5.31
Access mode
Display:
ACCS
Range:
OFF, EASY, NONE
or
ALL
Default Value:
OFF
Access mode - the access mode function
ACCS
has four possible settings namely
OFF, EASY,
NONE
and
ALL
. If set to
OFF
the mode function has no effect on alarm relay operation. If set
to
EASY
the “easy alarm access” mode will be activated. Refer to “Easy alarm relay adjustment
access facility” section. If set to
NONE
there will be no access to any functions via
FUNC
mode,
entry via
CAL
mode must be made to gain access to alarm and calibration functions. If set to
ALL
then access to all functions, including calibration functions, can be gained via
FUNC
mode.
5.32
Setpoint access mode
Display:
SPAC
Range:
A1, A1-2
etc.
Default Value:
A1
Setpoint access - sets the access via
FUNC
mode and “easy alarm access” mode to the alarm relay
setpoints. Two relays are fitted as standard, two more are optionally available. The following
choices are available:
A1
- Allows setpoint access to alarm relay 1 only.
A1-2
- Allows setpoint access to alarm relays 1 and 2 only.
A1-3
- Allows setpoint access to alarm relays 1, 2 and 3
A1-4
- Allows setpoint access to alarm relays 1, 2, 3 and 4
The remote input function (
R.INP
) must be set to
SP.AC
for this function to operate. Note:
Only the setpoints which have been given a value will be accessible e.g. if
A1Hi
is set to
OFF
then there will be no access to the
A1Hi
function when
SPAC
is used.
