Enclosure IP66 with Dual Door Access
The VP-KB1 is used in gas detection applications that require monitoring of analog transmitters. Standard features like 4x20 character LCD’s, LED alarm indicators,pushbutton interface, relay outputs, universal power supply with 24 VDC field power, and a comprehensive programmable sensor input types gives the VP-KB1 ultimate flexibility.
Standard Features
- Up to 8 Remote Transmitters (4-20 mA)
- Sensor Type Programmable - See Chart Below
- 4 Control Relays (SPDT 2A) Fault, Low, Mid and High Alarm
- Control Module Raspberry Pi Powered
- 4x20 Character LCD and 2 Bi-Colour Alarm Status LEDs
- IP66 Enclosure 13.78" High x 9.84" Wide x 6.3" Deep
- Separate Access Door for LCD Display Module
- 4 Function Keypad for User Interface
- 120/240 VAC Power Input
- 24 VDC 1.5 A Power Supply
Operation
Getting Started :
1. Mount the VP-KB1 controller in a suitable location for the application.
2. The power input relies on the installer to provide a suitable circuit breaker or fuse protection circuit.
3. Connect the remote sensor wiring. NOTE: 24 VDC field power is provided on the analog input module with available current of approximately 1 A. If more power for field transmitters is required, the user must install an appropriate separate power supply.
4. Connect the relay output circuits as required.
Power On :
There is a 20 Second Power On Timer to allow the processor tp boot up and stabilize. During the Power On cycle, the LCD will display the default VP-EC-RDU power on message:
Start Up Display
VP-EC-RDU
Press UP/DOWN/ENTER
Together
For Program Mode
There are 4 Main Display Screens. The different screens are accessed with the UP or DOWN Pushbuttons
Pushbutton Operation :
There are four pushbuttons, MENU, UP, ENTER and DOWN. The basic operation is UP or DOWN to select the display, ENTER to start or exit a function.
Status LEDs :
Status 1 LED Displays the alarm conditions of the sensors :
GREEN = OK
AMBER = Warning
AMBER FLASHING = Caution
RED = Critical
RED FLASHING = Sensor Fault
Status 2 LED Displays the alarm conditions of the Relays :
GREEN = OK (No relays energized)
AMBER = Alarm (One or more relays are energized)

Normal Operation LCD Screens :
Examples shown are for a NH3 (Ammonia) Sensor Input 1, all other sensor (2 thru 8) are disabled.
Each screen changes on either an UP or DOWN button press, the example shown is successive DOWN button presses.

Programming
To enter the programming mode, press the MENU (M) pushbutton :
The "Enter Password" screen will appear
1. Enter Password
Enter Password
0000
^
The default Password for the VP-KB1 is "2018"
To enter the password :
1. Used the UP or Down pushbutton to select the first digit
2. Press the ENTER ( [] ) pushbutton to accept the value and the cursor will advance to the next digit to be entered
3. Repeat steps 1 and 2 untill all the values are entered.
NOTE: These steps are used in all the programming steps that require a value to be entered.
Once the correct password has been entered, the programming screens will appear.
