10.4.13 Adjusting alarm setpoints from the
operational mode
Access to the alarm setpoints from the transmitter
operational mode is obtained by operating the
P
and
▲
push buttons simultaneously as shown in Fig 15.
If the setpoints are not protected by a security code
the alarm setpoint prompt 'SP1' will be displayed. If
the setpoints are protected by a security code, 'CodE'
will be displayed first. Pressing
P
again will enable
the alarm security code to be entered digit by digit
using the
▼
or
▲
button to adjust the flashing digit,
and the
P
push button to move control to the next
digit. If the correct code is entered pressing
E
will
cause alarm setpoint prompt 'SP1' to be displayed.
Pressing the
▼
or
▲
button will toggle between the
two alarm setpoint prompts 'SP1' and 'SP2'.
If an incorrect security code is entered, or a button is
not pressed within ten seconds, the transmitter will
return to the display mode.
Fig 15 Setpoint adjustment from the display mode

P
button to move control to the next digit. When the
required setpoint has been entered, pressing

will
return the display to the 'SP1' or 'SP2' prompt from
