 Press the number for the desired units.

3.4.4 TAG NUMBER

THE TAG NO.s ARE USED ONLY FOR NETWORK APPLICATIONS AND ARE USUALLY

FACTORY SET. To communicate on a network, each controller must have a unique Tag Number

(also called node address).

Important: if multiple units on a network have the same address, network errors will result.

An Arjay Central Access Panel (CAP) is required to communicate with 2000 series level

controllers on a network. The CAP allows data to be viewed from and remote calibration / set of

any 2000 series level controller on the network from a central location.

 Press the SETUP KEY if not already in the Setup menu, then press 3 for Settings, then 3 for

Tag #.

 Enter the desired tag number.

3.4.5 mA SETTINGS

 Press the CONTROL key:

**CONTROL SETTINGS**

1-Relay Settings

2-mA Settings

 Press 2 to setup the mA output:

***SET mA OUT***

Zero (% Lvl) 0.0

Span (% Lvl) 100.0

 Enter the level in percent for Zero and Span values followed by the Enter key in each case.

After the Enter key is pressed for the Span value, the following menu is displayed for

additional mA settings:

***SET mA OUT***

Action: Direct

Type: 4-20mA

Press 1 to change

 The cursor will be on the Action setting line. Pressing 1 toggles between Direct and Inverse

action. Direct action causes the 4mA to be output when the level is at the Zero setting and

20mA to be output when the level is at the Span setting. Inverse action is the reverse of

Direct action. Press the ENTER key when done.

 The cursor now drops to the Type setting line. Pressing 1 toggles between 4-20mA and 0-

20mA. The 0-20mA as the name implies, outputs a signal between 0-20mA instead of 4-

20mA. The 0-20mA setting generally offers a little better measurement resolution.
