Cooling System Monitor (509ITM-200)
There are two parts to the Cooling System Monitor. The first is the setup described in the
Software Instructions under
Cooling Monitor Initialization
. Make sure you have familiarized
yourself with these sections before using the Cooling Monitor feature.
The second part of the Cooling System Monitor is the normal operations of the Cooling
System. Once the cooling feature has been initialized and configured, the 509ITM will begin
monitoring the cooling system. The automatic scrolling display will show the current of the
cooling fan/pump, the status of the flow gauge, if there is one, and, if selected, the
temperature of both the RTD inputs and their differential value.
When the cooling system is inactive, the operator will view a zero value for the measured
current. This will not cause the cooling alarm relay to actuate because the cooling system
only uses the active inrush and steady-state current values for comparing against high and
low set point values.
To be able to view the active values and their maximum and minimum values, the operator
needs to press
MENU
to enter the MENU Mode. When in the MENU Mode (see the
for a visual overview of the MENU Mode) the operator can go to the cooling
monitor column. If the header of the column displays that the cooling monitor is inactive, the
cooling monitor has either not been installed or the user did not make it active. (
for making a cooling bank active
If the cooling bank is active, the operator can travel up and down the column to view the
present active values, maximum and minimum values, set points, actuation counts, total run
time, and the differential set point amount. When viewing the maximum and minimum values
the user can reset them by pressing
RESET
when they are in the cooling mode column.
Note:
If more than one cooling mode is active, the user should view all of the values before
resetting them because, when pressed,
RESET
will clear the entire maximum and
minimum current values once it is pressed.
If enabled, a current value will activate the alarm, but it is possible to enter the MENU Mode
and reset the active current values to their average learned value. When moving down the
cooling mode column, the operator will view a window for each active cooling bank that
reads: “COOLING CURRENT CMX <RESET>”. While viewing that window, press
RESET
to
cause the inrush current value and the running current value of only this particular cooling
bank to restore the average values as present values. This feature is in place in the event
that the operator knows of a failure or has fixed a failure and wishes to stop the alarm until
the cooling system can engage again and measure new values. By pressing
MENU
, the
operator can exit the MENU Mode.
