INSTALLATION
For each output:
1.
Remove the terminal block fitted into the analog output socket.
2.
Strip back the wire for the common (black) connection to the
CH1
output,
exposing approximately 0.25" (6mm) wire insert the wire into the
COM1
terminal way and screw into the block.
Do not overtighten the screw.
3.
Strip back the wire for the signal (e.g. red) connection to the
OP1
output,
exposing approximately 0.25" (6mm) wire, insert the wire into the
OP1
terminal way and screw into the block.
Do not overtighten the screw.
4.
Repeat operations 1 and 2 for the other analog outputs, selecting a different
color wire for the
OP2
and
OP3
outputs.
5.
Locate the terminal block over the connector labelled
ANALOG OUTPUTS
and push the terminal block firmly into the connector.
2.5.3 Alarm Output Connections
Two alarm outputs are provided from a terminal block, located on the rear panel of
the instrument, as two pairs of potential free, change-over relay contacts. These are
designated as a
PROCESS
alarm and a
FAULT
alarm.
The
PROCESS
alarm can be configured to represent any one of the measured or calculated
parameters and set-up to operate when a pre-set parameter threshold level is exceeded. By
default, the
PROCESS
alarm is set to monitor the dew-point parameter. See section 3.2.4 for
further details.
The
FAULT
alarm is a non-configurable alarm which continuously monitors the degree
of contamination of the chilled mirror. During normal operational conditions this alarm
will be off. If the optics or the mirror contamination exceeds 100% of the film thickness,
or if a fault exists on the Pt100, the alarm is triggered and the relay contacts will change
state.
This fault is also reported to the status area of the display.
The two alarm output ports are connected to the instrument via a single 6-way, push-fit
connector block as shown in
Figure 5. Each output comprises a 3-wire set of potential
free, change-over relay contacts.
Each contact set is labelled
COM
(common 0 V),
N/O
(normally open with respect to
COM
) and
N/C
(normally closed with respect to
COM
).
To differentiate between the alarm output channels it is recommended that a black lead
be used for each of the
COM
(common) lines and a separate color for each of the
N/O
and
N/C
lines.
