2. Instead of green lights for the monitors on both the web probe status screen and the
front panel quad screen, the monitor in alarm condition will turn red. Control-type
monitors will go from green to yellow when activated.
3. Alarm events will be written into the Alarm Log, including when the alarm was
activated, when acknowledged, and when returned to normal mode.
In summary, if you wish to the front panel to show an alert on the front panel, use the alarm
monitor; if you only want to activate a relay or email, use the control monitor.
There are eight standard choices of monitors, plus the Analog Output when the optional
analog output card is present (see Section 13.4). From Figure 14 above, they are listed here
with explanations:
• High Control Activates relays and/or notifications upon reaching a high level
• Low Control Activates relays and/or notifications upon reaching a low level
• Fill Control Deactivates relays and/or sends notification upon reaching a
high level
• Empty Control Deactivates relays and/or sends notification upon reaching a low
level
• Low Alarm Same as Low Control but with alarm functions
• High Alarm Same as High Control but with alarm functions
• In Range Alarm Activates alarm and relays and/or notifications upon reaching
either a high or low level defining a range
• Out of Range Alarm Activates alarm and relays and/or notifications upon reaching a
level inside of a defined range from either direction
Choosing one of these Monitor Types leads to modifications of this screen, walking the user
through the selection of the data needed to set the monitor. Figure 15 shows the pull-down
menu for the Relay Number when “High Alarm” was selected for the Monitor Type. There are 4
relays to select from normally, but in this example, three have already been configured and
only Relay 4 is available. Adding an optional expansion board adds another 4 or 8 to this
menu. If a relay is already being used as here, it may not be selected and must first be freed up
as a monitor from the specific probe it is linked to.
There are also choices for Email Only and Display Only that allow the monitor to react to the
probe conditions without activating a relay. Display Only will set up a green light on the front
panel for the monitor (and on the web Probe Status screen), turning red if an alarm or yellow if
a control.
If a relay is selected, clicking on Show Relay will bring up an image of the rear of the 2300
Controller with the corresponding contacts outlined in red. This is for information only, as the
Controller should be powered down when being wired, or the wiring should be done to the
disconnected connector if the unit is not powered down. This feature is very useful with the
optional relay cards to show how to wire up the relay; it is shown in Figure 16. In this figure,
there is a six-relay card and a four analog output card shown. Only Relays 2 and 4 are available
for selection as the others are previously defined.
