3.1 Installation
The Host to Supervisor Cable has one of several connectors (P1), which is meant
to interface directly to the furnace MFC port. Compare the pin assignments for the
Host to Supervisor cable with the furnace controller interface port prior to making
the connection. The other end of the cable has a 9-pin d-shell connector (P2),
which plugs into the Supervisor. To make the cable connection to the Supervisor,
align the keys and insert the connector. Secure the connector. Connect the P1
end of the cable to the designated unused MFC port. Secure the cable with tie-
wraps or other strain relief fasteners.
RS422/RS485 Serial Connection with Separate Power Supply
In this configuration, the SENTRY system derives its power from a stand-alone
power supply. The power cable set is based on the voltage available, and is de-
signed for DC voltage or standard AC power connections. Section 7, page 1.
gives part numbers for cables of different voltages. The Serial Interface Cable has
an RJ12 modular connector, which interfaces with the Supervisor. (see Figure 3-
6). The other end connects to the host.
I Note: Use of the serial connection with the SENTRY 1510 is not CE
compliant.
Testing the Installed SENTRY 1510
Prior to performing process tests with the new SENTRY 1510 exhaust system in-
stalled, it is recommended that an initial series of tests be performed to ensure that
the system has been installed correctly and is functioning properly. The first test
(see section 3, page 10.) is to use the Supervisor in "local" mode to set a process
pressure level using the keypad, and to observe that the SENTRY 1510 is able to
achieve a stable process pressure for the diffusion furnace. The second test (see
section 3, page 12.) is to operate the Supervisor in "remote" mode and observe
that the furnace controller is able to send a set point signal to control the SENTRY
system. Once the installation tests are completed, the SENTRY 1510 can be used
for process test runs.
Before installation tests are performed check to be sure that there is sufficient
house exhaust (see section 3, page 3.) connected to the output of the SENTRY
1510. Verify that the nitrogen supply to the SENTRY 1510 is turned on with 35 to
100 psi of pressure available. Also, verify that all cable connections are secure on
the Supervisor and on the SENTRY 1510. Turn on system power to the
Supervisor by depressing the power switch to the ON position (see figure 3-5).
Ensure the boat is loaded in the tube and the door sealed.
I Note: Ensure the boat is loaded in the tube and the door sealed. Closing
the shutter is not sufficient for testing.
