50-604 Kotron Model 804 Sentinel II RF Level Transmitter

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.

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:
