2.4.2.4 Manual self-test
A manual self-test can be performed on the 804 electron-
ics. A remote contact should be wired across terminals
1 and 2 with terminal 3 used for shield if needed.
Performing a manual self-test will cause the 804 to go into
alarm mode. The relays and mA output will change to the
mode selected in the Unit Configuration.
2.5 Unit Configuration
2.5.1 General Configuration Instructions
The Kotron Sentinel II RF Capacitance Level Transmitter
contains a microprocessor-based operator interface, which
allows easy configuration of level measurement or control
applications. These simple-to-use features are accessed
through the 16-digit keypad, located on the front of the
unit’s shield.
The operator interface and instructions for the unit config-
uration are broken down into five main groups of menus:
MEASURED VALUES:
For viewing the measured values
SYSTEM CONFIG: Probe calibration
I/O CONFIG: Configure the input/output functions
(such as 4–20 mA and relays)
ADV CONFIG: Set the unit’s advanced features
(such as password and display options)
DIAGNOSTICS: Enhanced troubleshooting features.
2.5.2 Password
The Sentinel II has a built-in password system to restrict
access to portions of the menu that affect the unit’s opera-
tion. The password is required whenever programming
values are being changed. The password can be changed to
any four digit number desired. This procedure is described
under the
ADV CONFIG menu page 13.
Caution: The Sentinel II is shipped from the factory with the pass-
word 0804. If the programmed password is misplaced or
forgotten, consult the factory for assistance.
2.5.3 Operator Keypad
All unit configuration instructions in this manual will
show the local transmitter display exactly as it will appear
to the operator. The operator interface is via a keypad
consisting of the following keys:
