1.INTRODUCTION
1.1.APPLICATIONS:
You can achieve the following measurements and applications with the device.
- All measured parameters can be transferred via RS485 line with MODBUS protocol and menus can be
set remotely. (DCV-10S/10CS/11S/11CS)
-With 2 programmable Alarm Relays, a range in which the monitored system voltage should reside can
be determined and a warning signal can be created for the user with Alarm1 (C1) and Alarm2 (C2) contact
outputs if this monitored voltage goes out of the determined range. (DCV-10C/10CS/11C/11CS)
- With a programmable Analog Output, the device can be programmed to give a voltage or current output
according to the measured voltage value. (DCV-10A/11A)
-Measured maximum-minimum values can be monitored by using UP/DOWN buttons.
-Settings can be accessed easily and read comfortably with the back-lit LCD feature.
- Measurement results can be calculated in a desired time with an adjustable measurement period of 1-
600 s.
-The device provides flexible usage with wide supply voltage range. 85-265 V AC/DC
(DCV-10/10A/10C/10S/10CS), 10-56V DC (DCV-11/11A/11C/11S/11CS )
- The device settings can be protected from changes by unauthorized personnel by specifying a 4 digit
user password.

Modbus Functions:
The T times corresponds to a time in which data must not be exchanged on the communication bus
to allow the connected devices to recognize the end of one message and the beginning of another.
This time must be at least 3.5 characters at the selected baud rate. Adress range (1-247) is address
of the connected device. The data field contains data sent to the slave by master or data sent to
master by slave. CRC is a error check method by using MODBUS RTU protocol and consists of 2

2.2.5 RESET Reset Menu
Minimum and maximum values among measured voltage values are stored on the device. Reset menu is
used in order to delete these values. There are 2 sub-menus under Reset menu: RESET MIN, RESET

NOTE: Stored values are not affected from power outages. Measured minimum and maximum values are
deleted after you select YES option under the value that you want to reset and approve the changes when
you exit or a zero (0) value is written into the addresses that these values are stored.
Preset Single Register (06H) function is used for change device settings and resetting the measured
