During value entry, the capacitance and level are still being constantly updated in the background.
Apart from the CALIBRATION menu and the DIAGNOSTICS menu, in all other menus, the Alarm
relays and the mA output are also updated.
3.2 2300 SERIES USER INTERFACE
Please skip this Section for 2100 series models which have an integral keypad and LCD.
As described, the 2300 series models lack an LCD and keypad. To access these models, an Arjay
Central Access Panel or Handheld Calibrator is required.
The CAP or Handheld communicates with any 2000 series level controller via a multidrop RS-485 /
modbus protocol. For models with an integral keypad and LCD, the network is optional. For 2300
series models, the network is standard.
Up to 100 2000 series level controllers may be connected to the network. Each must have a unique
node address i.e. any number from 1 to 100.
The CAP or Handheld Calibrator accesses any desired 2300 series level controller on the network for
data access, calibration, and setup. The display on the CAP or the Handheld is identical to the
menu’s and displays described below except for 2 major differences:
1. The node address and model number of the currently accessed 2000 series level controller is
always displayed on the topmost line of the LCD.
2. The node address may be changed (i.e. another controller on the network may be accessed)
by pressing the ENTER key from the top level of any main menu. The top level is the first
menu after pressing any main menu key. There are 4 main menus: Display, Calibration,
Control, and Setup. Pressing ENTER from a top level menu, brings up the following screen:
REMOTE XMTR SELECT
Address: 1
Where the Address on the 2
nd
line prompts with the currently selected node address. Enter the new
address and press the ENTER key to confirm the entry. The unit automatically reverts to the
previous menu.
The Handheld Calibrator runs on a 9V battery and therefore includes a Low Battery warning which is
displayed on the LCD. The warning is only displayed in the normal DISPLAY mode.
Refer to the figure below for connecting the Handheld Calibrator to the 2300 series models.
