Special Functions for Buttons

UP button: In monitoring mode, it is used to display the maximum current value.

In program mode, it is used to change the device parameters.

SET button: When it is pressed for 3 seconds, the user enters MAIN MENU. It is then used to

enter SUB MENUs from the MAIN MENU and to save the changes in parameters. If Latch function is active, it opens the alarm output contacts when the system current leaves the programmed range. When the current enters the programmed range, alarm output contacts dont close (lock-hold). Output contacts are closed by using the SET button.

DOWN button: In monitoring mode, it is used to display the minimum voltage value.

In program mode, it is used to change the device parameters.

1.4 HARDWARE FEATURES

- Current measurement connector (2-pin, I+, I-)

- 0/2-10V, 0-4/20 mA Analog Output connector (3-pin, V, GND, I)(DCA-10A/11A)

- RS-485 connector (4-Pin)(DCA-10S/10CS/11S/11CS)

- 2 Relay connectors ( 4-pin)(DCA-10C/10CS/11C/11CS)

- Supply input (2-pin) (85-265V AC/DC (DCA-10/10A/10C/10S/10CS), 10-56V DC (DCA-11/11A/11C/11S/11CS))

2- USAGE OF DEVICE:

2.1 MENU USAGE AND SETTINGS:

After the device is installed according to the connection diagram in the user manual, energise the device.(Refer to: Connection diagram) In order for the measurements and applications to be accurate, necessary adjustments must be made by using menus.

2.2 MAIN MENUS:

There are 10 main menus on the device for measurement and usage settings. The user can access MAIN MENUs by pressing the SET button for 3 seconds on measurement screen. By pressing the SET button on any MAIN MENU, SUB MENUs of the related MAIN MENU is entered. Note: In order for a change that you committed in the menu to be in effect, you must give approval for those changes when exiting the menu. Otherwise, changes will not be in effect.

2.2.1 SHUNT MENU

Current and voltage values of the external shutn resistor which will be connected to the device to measure the current is set in this menu. There are 2 submenus under SHUNT menu.

SHUNT C, SHUNT V.

SHUNT C Shunt Current Setting Menu

The current value of the shunt resistor which will be connected to the device is entered in this menu. Shunt current can be entered between 1A and 10000A (10 kA). When this parameter is changed, maximum and minimum current values stored up until that time are deleted. Note: The shunt that you will connect to the system must have a current characteristic 1.5 times than the current need of your system. Example: If your current need is 100A, the minimum current value of the shunt that you will connect must be 150A. If you connect a 100A shunt to a 100A system, it may cause the shunt to burn up over time. Additionally; in order for the shunt to be compatible with the measuring class of the device, it must be minimum 0.5% class. Otherwise, you cant obtain a 0.5% accuracy with the measurements made with the device.
