Easy alarm re lay ad just ment ac cess fa cil ity
The PM4-RT8 has an easy alarm access facility which allows access to the alarm setpoints simply
by pressing the
F
button at the front or rear 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). For further details of analog PI easy setpoint access refer
to the separate “PM4 Panel Meter Optional Output Addendum” booklet supplied when this option is fitted.
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
SP.AC
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
SP.AC
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 then 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 unless the instrument is powered up in
CAL
mode.
