1 Castello Overview
Castello provides a user-friendly way of showing the pressure measurement at the bottom of a tank as the remaining quantity of liquid. At the push of a button, the microcontroller performs calculations based on information about the tank's shape and dimensions so that the remaining tank content (liters, gallons etc.) is shown on the easy-to-read 5-digit LED display.
The unit is configured using a PC and user-friendly software, so the level (which determines the pressure) can be converted into the relevant quantity in the tank (in liters, gallons etc.). The tank shape is selected first, and then the tank dimensions and the liquid's specific density are entered. The program contains the most common tank shapes, but also allows users to generate any tank shape by entering its parameters in a specification table.
The Castello system makes exclusive use of absolute pressure transmitters, so capillary vented cables are eliminated, thus making the Castello very rugged and suitable for reliable applications in humid and wet environments.
An air pressure sensor (range: 0.8 bar to 1.2 bar absolute [abs]) is integrated in the Castello housing. The transmitters to measure hydrostatic pressure at the bottom of the tank are calibrated from 0.8 to 1.8 bar abs for tanks up to 5 m in height, and from 0.8 to 2.3 bar abs for tanks up to 10 m in height. The pressure differ­ence, calculated by the microcontroller, is the relative hydrostatic pressure.
The content of a pressurized tank is determined from the difference between the measurements taken by two absolute pressure transmitters located at the top and bottom of the tank.
The system achieves overall accuracy of 2 mbar thanks to a computerized calibration and compensation procedure for the pressure transmitters Series 23Q and 26Q. The coefficients for this calculation are stored in EEPROMs in the transmitters. These are retrieved by the microprocessor when each measurement is taken, and are used in the equations to calculate the pressure values. Because these coefficients are stored in the transmitter, the Castello housing and the hydrostatic transmitter can be exchanged at will with no need for additional configuration or data entry.
It is also possible to connect a standard 3-wire transmitter with voltage output (0…5V), or a high-precision digital transmitter (series 3X) that can be configured to an accuracy of 0.02% FS over a range of 0 to 50°C; this transmitter is read by Castello via the RS485 interface.
The power supply to the system (8 to 28 VDC) can be provided externally, or internally with a 9 V battery. Castello’s display is powered for a configurable duration by pressing the button on the front of the Castello. The Castello has two switch outputs with configurable functionality and threshold values. An external power supply must be provided if the switch outputs are to be used.
Installation The housing has two holes to mount the unit. The transmitters are easily installed by removing Castello’s
cover plate, leading the cable through the PG screw connections, and then connecting the transmitter wires to the appropriate screw terminals. The Castello is programmed via the connector on the side, which equally serves as external power supply and switch output connections. Once the cover plate is installed and the cable lead through connections are properly tightened, the extremely robust housing is watertight to IP65.
PC Configuration Software
The software to configure Castello can be downloaded from our website or ordered on CD (handling charge payable). Castello can be connected to the PC via KELLER converter cables K-107 (RS232) or K-104B (USB) with adapter. The software contains the calculations (pressure/content curves) for several tank shapes. The dimensions of the tank, the density of the liquid and the measuring unit of the display are set in the software for the selected tank shape.

2.4 Castello Housing Dimensions and Interface
Transmitter Connection
A maximum of two transmitters can be connected to Castello via a cable gland (PG connector).
Air Pressure Sensor
The built-in air pressure sensor can be used to compensate air pressure changes when an absolute pres­sure sensor is used to measure the content of a vented tank.
Display of Switch Outputs (LED)
The LEDs show the current state of the switch outputs (if they are activated).
External Supply
The device can be supplied from an external power source. If the switch outputs are used (activated), the instrument must be supplied with an external DC voltage of 8 … 28 volts.
Switch (Relay) Outputs
The relay outputs can handle up to 28VDC / 0.4A. The built-in relays have insulated inputs and outputs.
RS485 Interface
The RS485 interface allows the user to configure and communicate with the Castello (i.e. read current val­ues). Up to 128 instruments can be addressed via the KELLER BUS protocol. Please consult our website for a description of the BUS protocol to create custom software, as well as the PC software for graphic display of the current measurement values.

3.4 Connecting Series 3x Transmitters with the RS485 Interface
The RS485 interface enables communication with Keller digital instruments (transmitters, data loggers etc.). Connect RS485 A (Pin 1) and RS485 B (Pin 2) to the Castello.
A maximum of two Series 3x transmitters can be connected to the Castello by selecting "Series 30" in "Types of transmitter settings" (Castello Setup). If two S30 transmitters are to be used, each transmitter's address must be configured with a unique address (use Prog30 Software to configure the bus address): Set transmitter 1 to bus address 1, and set transmitter 2 to bus address 2. If only one S30 transmitter is connected, it is not necessary to set the bus address.
We recommend using Series 30 transmitters from Keller with the low power and low voltage option to reduce battery consumption (in this case, connect the transmitters to the 5 V power supply).
Connect Series 3x Low Power / Low Voltage transmitters
The picture below shows the connection for a Series 3X transmitter with the low power / low voltage option. These transmitters can be supplied with a voltage range of 4V … 12V. The transmitter supply should be connected to the 5V clamp.

Transmitter 2

Connect Standard Series 3x Transmitter
The standard Series 3X transmitters have a supply in the range from 8V to 28 V. In this case, you should connect the transmitter supply to clamp 15 (transmitter supply: 18 volts).
Connect the transmitter to clamps 7 & 8 & 13 & 14. If only one transmitter is connected to the relevant clamps, the BUS address does not have to be set.
The second transmitter is connected using the same clamps as transmitter 1 (connect them in parallel). Both transmitters must have been configured with BUS ad­dresses 1 and 2.

5.4 Tank Calculation
For all the different tank types, properties, and settings, "Castello Setup" calculates a table and writes it to Castello's EEPROM. The microcontroller then measures the current pressure (level) and searches the table for this value. The microcontroller interpolates a polynomial over 3 measuring points, calculates the tank content and shows it on the display.
Tank settings are also stored in the Castello.

6 Configuring the Switch Outputs
To configure the switch outputs, the separate "Pressure Switch Console" software must be used. If switch outputs are enabled, an external supply should be used to power the Castello, since the display is then in continuous mode and the battery will consequently discharge rapidly.
Disabling the switches (setting them to Off) will return Castello to standard mode (i.e. power down the dis­play after the configured delay).
6.1 Switch Outputs with Switch Time Delay
If a switch delay is set, the corresponding Castello LED switch indicator starts flashing when the switch setpoint is reached and the time delay countdown starts. When the switch time delay is reached, the LED stops flashing and shows the corresponding switch state.
LED on = switch closed LED off = switch open LED flashing = switch delay is counting, and switch state is set after the delay
