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.
