Grounding of the temperature sensor shield

temperature sensor while the controller is still powered up. Under these conditions, as additional
protection against electric shock, it is recommended that the shield of the temperature sensor be
grounded.

Installation requirements for EMC

•

installation precautions are necessary. When using relay or triac outputs, it may be necessary to fit a
filter suitable for suppressing the emissions. The filter requirements will depend on the type of load. For
typical applications, it is recommended to use Schaffner FN321 or FN612.

Routing of wires

•

routed away from high-current power cables. This will minimize the pick-up of electrical noise. When it
is impractical to do this, use shielded cables with the shield grounded at one end.

About the Model 9120 – RPS

The Model 9120-RPS is specifically designed to read two SSi Gold Probes, installed in the same furnace.
The Model 9120-RPS controller, a 24 VDC power supply, and two 24 VDC relays are mounted and wired on
a piece of DIN rail for easy mounting. Two other components included with the Model 9120-RPS are the
operator interface and the cable connecting the operator interface to the Model 9120-RPS.

Electrical Installation

The Model 9120-RPS comes mounted on a DIN rail, pre-wired and tested. AC power needs to be connected
to the 24VDC power supply. See the section

Model 9120-RPS Function

The Model 9120-RPS reads a signal from each of the two oxygen probes located in the furnace. Depending
on the 9120-RPS configuration, it will select whichever millivolt reading it has been configured (high or low)
to select and retransmit this millivolt output to the atmosphere controller.

The probe millivolt deviation band and the alarm delay times are set using the operator interface. See the
section
connected per the electrical drawing (section
configuration is set to retransmit the millivolt signal from the probe with the highest millivolt output. As
time passes and if/when the other probe’s millivolt output becomes greater (dependent on the deviation
band), the Model 9120-RPS will switch the output from one probe to the other and send the “new” higher
(or lower, depending on the configuration) millivolt signal to the atmosphere controller. The deviation band
must be exceeded for the retransmit to occur.

The black millivolt value on the operator interface display indicates which probe’s millivolts are being used
by the furnace atmosphere controller.

The operator can manually select the probe that is to be used in the carbon calculation. If this feature is
used, the 9120-RPS will use the operator-selected probe, and NOT switch from one probe to the other
automatically. See the section
manually select a probe.

The deviation alarm is disabled if both probes’ millivolts drop below 950. This should eliminate the nuisance
alarm when the furnace is loaded and the temperature drops.

Main Overview Screen

The Main Overview screen will be the initial screen that is displayed when the RPS is first started up. The
Main Overview screen will display: the two probes’ millivolts values, as well as the Menu button and the
Chart button. The active probe will be displayed in Black, while the inactive probe will be displayed in

Gray. Any activated output will be lit up on the RPS unit. Any error or message will be displayed above the

Menu and Chart buttons.
The list of runtime messages is:

• Probe

The list of error conditions is:

• Both inputs less than 950 mV – Neither probe can be selected when both inputs are less than
950 mV.
