Easy alarm relay adjustment access facility
The display has an easy alarm access facility which allows access to the alarm setpoints simply
by pressing the
F
button at the front of the instrument. The first setpoint will then appear
and changes to this setpoint may be made to this setpoint via the
^
or
v
buttons. Press the
F
button to accept any changes or to move on to the next setpoint. Note: this easy access also
functions in the same manner for the PI control setpoint (relay and/or analog PI output) if PI
control is available. The instrument must be set in the manner described below to allow the easy
access facility to work:
1. The
R.INP
function must be set to
SPAC
or the
ACCS
function must be set to
EASY
.
2. At least one alarm must have a setpoint, nothing will happen if all the alarm setpoints are
set to
OFF
.
3. The
SPAC
function must be set to allow access to the relays required e.g. if set to
A1-2
then the easy access will work only with alarm relays 1 and 2 even if more relays are fitted.
4. The instrument must be in normal measure mode i.e. if the instrument is powered up so that
it is in
CAL
mode then the easy access will not function. If in doubt remove power from the
instrument, wait for a few seconds then apply power again.
5. If the easy access facility is used then the only way to view or alter any other function
settings is to power up via
CAL
mode i.e. there is no entry to
FUNC
mode functions unless
the instrument is powered up in
CAL
mode.
