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.

Alarm relay 1 low setpoint
Display:
A1Lo
Range:
Any display value or
OFF
Default Value:
OFF
Displays and sets the low setpoint value for alarm relay 1. Use this low setpoint function if a relay
operation is required when the display value becomes equal to or less than the low setpoint value. To set
a low alarm value go to the
A1Lo
function and use the
^
or
v
push buttons to set the value required
then press
F
to accept this value. The low alarm setpoint may be disabled by pressing the
^
and
v
push buttons simultaneously. When the alarm is disabled the display will indicate
OFF
. If the relay is
allocated both a low and high setpoint then the relay will activate when the value displayed moves outside
the band set by the low and high setpoints. The value at which the relay will reset is controlled by the
A1HY
function.
Example:
If
A1Lo
is set to
10
then relay 1 will activate when the display value is 10 or less.
