Configuration – Alarm Delay
The
Alarm Delay menu screen will display the number of minutes that an alarm can be delayed before
switching the probe output from one probe to the other (default = 20 minutes). To change the value,
press the ENT key. The rightmost digit will begin flashing. Pressing the CLR key will display the value as
0. Pressing the up arrow key once will display the value as 1. Pressing the up arrow key once again will
increment this value by one. Enter the new value as desired. Pressing the ENT key will set the entered
value. Pressing the NEXT key will display the Probe Select (Prb) Mode menu screen. Pressing the PREV
key will display the Deviation Band menu screen.
Note: There is a 950 mV low limit for an alarm. This condition is typically found during a burnoff, so the
alarm will not be active when the input drops below 950 mV .
Example – The following example will show how to set the alarm delay from a value of 5 min to a value of
10 min. Press the ENT key. The 5 will begin flashing. Press the up arrow key once so that a 1 is
displayed. Press the left arrow key once so that a 10 is displayed. Press the ENT key to set the value.
Note about Alarm Delay – the valid range of values for the alarm delay is 0 to 60 minutes. Any value
entered over 60 minutes will be set to the last set value by default.
Configuration – Probe (Prb) Select Mode
To select the probe that you want to use to establish the % Carbon on your carbon controller you can do
one of two things. One, a three-position selector switch can be installed as shown on the electrical
drawings (see Typical Electrical Drawing ) -the left-position is Probe 1, the middle position is AUTO, and the
right-position is Probe 2. Two, press the ENT key. The default selection is 0 – Auto – Highest.
Once the ENT key has been pressed, the left digit will be flashing. This digit represents the mode for the
RPS unit. The possible digits/modes are:
0 – Auto – Highest *This will select the higher value when one of the probes goes out of band
1 – Auto – Lowest *This will select the lower value when one of the probes goes out of band
2 – Manual *This option allows the user to manually select a probe to use.
Press the up arrow key for the desired option, then press the ENT key to set the value. Pressing the NEXT
key will display the Manual Probe (Prb) Select menu option. Pressing the PREV key will display the Alarm
Delay menu screen.
Example – The following example will show how to set the probe selection mode from a value of 0 (Auto –
Highest) to a value of 2 (Manual). Press the ENT key. The 0 on the left of the screen will begin
flashing. Press the up arrow key twice so that a 2 is displayed (The “Auto – Highest” will not be replaced
until the new mode has been set). Press the ENT key. The screen will now display 2 Manual. Note
about probe selection mode – Although the numbers will cycle from 0 to 9, the only valid values are 0, 1,
and 2. Any value higher than 2 will be set to the last set value by default.
Configuration – Manual Probe (Prb) Select
The Manual Probe Select menu option allows the user to select a specific probe to use. The probe selected
will override the automatically selected probe. If in AUTO mode, the system will continue to select the
configured probe when the deviation band is exceeded. To run continuously in MANUAL mode, you must
first select the MANUAL mode from the Probe Select Mode menu (described above). To select a specific
probe, press the ENT key. The right digit will begin to flash. Pressing the up arrow key will reset the value
to 1. Press the up arrow key until the desired probe is reached. Once the desired probe has been selected,
press the ENT key to set the value. Pressing the NEXT key will display the initial display screen. Pressing
the PREV key will display the Probe (Prb) Select Mode menu screen.
Example – The following example will show how to set the manual probe selection from a value of 1
(Probe 1) to a value of 2 (Probe 2). Press the ENT key. The 1 in Probe 1 will begin flashing. Press the
up arrow key twice so that Probe 2 is displayed. Press the ENT key to set the value. Note about Manual
