AMALGAMATED INSTRUMENT RM4-IV, Operation And Instruction Manual

Page: 30 / 49

Lo
- valley (min.) memory mode. When
Lo
is selected and the remote input is set to valley
memory (
Lo
) then the alarm relay will be activated if the valley memory value is below the
low setpoint value. The alarm will not de-activate until the memory is reset.
dISP
- display mode. When
dISP
is selected the alarms will operate purely on the display
value at the time i.e. if the display is showing above high setpoint or below the low setpoint
value then the alarm relay will activate.

LiuE
This section describes the operation modes available for the retransmission options
REC
(analog
retransmission) operation mode. The following choices are available:
LiuE
- live input mode. The retransmission will follow the electrical input and will not necessarily
follow the 7 segment display. For example if the remote input is set for peak hold operation then
when the remote input is closed the 7 segment display will only show the peak value but the
retransmission will be free to change to follow the electrical input.
tARE
- tare mode. The retransmission value will tare (fall to zero) along with 7 segment display
when the remote input tare function is operated. If the remote input toggles the 7 segment display
to show gross (
GROS
) then the 7 segment display will change to show the gross value but the
retransmission will not respond (see
LiuE
for alternative operation).
P.HLd
- peak hold mode. The 7 segment display and retransmission value will indicate the peak
value only whilst the peak value function is operated via a contact closure on the remote input
i.e. the 7 segment display and retransmission can rise but not fall whilst the remote input switch
is closed. When the remote input switch is opened the retransmission value will remain fixed
i.e. it will not rise or fall, although the 7 segment display value will be free to alter. This peak
retransmission output can be cleared by closing the remote input switch for another operation or
by removing power from the instrument. Note: In this mode the retransmission will show a zero
reading until the remote input is operated for the first time after switch on.
d.HLd
- display hold mode. The 7 segment display and retransmission value will be held whilst
the remote input display hold switch is closed. When the switch is opened the retransmission value
will remain fixed at the held value although the 7 segment display value will be free to alter. The
held retransmission output can be cleared by closing the remote input switch for another operation
or by removing power from the instrument. Note: In this mode the bargraph will show a zero
reading until the remote input is operated for the first time after switch on.
Hi
- peak (max.) memory mode. With the peak remote input switch open the retransmission
will indicate the peak value in memory i.e. the retransmission output can rise but not fall. The
retransmission output can be reset by clearing the memory. The memory may be cleared either
by closing the remote input switch for approximately 2 seconds or by removing power to the
instrument.
Lo
- valley (min.) memory mode. With the valley remote input switch open the retransmission
will indicate the valley (min.) value in memory i.e. the retransmission output can fall but not
rise. The retransmission output can be reset by clearing the memory. The memory may be cleared
either by closing the remote input switch for approximately 2 seconds or by removing power to the
instrument.
