Single Phase Voltage Regulator RAV-2
with control CTR-2
Instruction Manual MI-010
Page: 25/27
Rev. 06/2017
If the function is set to " 0", the time delay until the motor is activated for the first tap change is always the same and
equal to the time set in functions 05, 10 , 21 and 35 for the active map.
However, if set to "1" , the CTR -2 control will set a new delay timeout depending on what time has been
programmed in the active map and the difference between the measured voltage and the reference voltage
programmed on the same map according to Tef = T x ( Ins / | Vref - Vavg | ) equation, where:
" Tef " is equal to the effective time delay of the drive ;
" T" is delay set on active map ;
" Ins" is insensitivity set on active map ;
" Vref " is the programmed voltage to the active map ( including securities of LDC) ;
" Vavg " is the instantaneous voltage measurement.
52 – Regulator operation mode
Changing the operation mode from manual to automatic for CTR-2 regulator. If configured in “0” it works on
automatic mode, if set to “1” manual mode:
53 - Serial communication address.
As the communication ports allow simultaneous connection of more than one control to a single supervisor system,
programming an address on each CTR-2 is needed to ensure there are no communication conflicts. This value can
be adjusted between "00000" and "65535" and the communication program ITBComm3 locates the control
connected with the selected target address "00000". Regulators with addresses between 00001 and 65535 will have
to be seeked manually on ITBComm3.
54 - Port 1 communication mode
The CTR-2 control has 2 simultaneous communication ports doors, including COM1. COM1 can be used in any of 3
possibilities, which are "0", "1" or "2". Using this set to "0" the front door DB9 jack communication port is available
for serial EIA 232 communication; Using this set to "1" COM1 the front door USB-A jack communication port is
ready for serial connection. Using this parameter set to “2” internal DB9 jack communication port is available for
serial EIA 2323 communication.
55 - Port 2 communication mode
The CTR-2 control has a second simultaneous communication port named COM2. Similarly to the COM1, COM2
can be used in two patterns of different outputs which can be programmed through this parameter by selecting an
option to "0" or "1". Using this set to "0" COM2 is available for serial EIA 485 communications available in accessible
terminals 36 (D-), 37 (D +), 38 (PTT +) and 39 (PTT) of terminal blocks inside control box. Using this set to "1"
COM2 is ready for optical connection by ST type sockets located in the internal superior part of control.
56 and 57 - Data transmission bound rate.
COM1 and COM2 of CTR-2 can have independent transmission rate configuration and this are set on parameter 56
for COM1 and 57 for COM2 with values adjusted from 0 to 7 as described in table 14
Table 14: Options of baud rate.
Value
0 1 2 3 4 5 6 7
Rate [kbps]
2,4 4,8 9,6 14,4 19,2 38,4 56 115,2
58 – Enabling unsolicited message
CTR-2 allows unsolicited message generation in DNP-3 and in this parameter control is configured if supervisory
system where this is installed accepts this or not. If value is set to “0” no unsolicited messages will be sent. If set to
“1” control will send a message any time a digital variable changes state
59 - Address for unsolicited message.
Once parameter 58 is programmed to send unsolicited messages, CTR-2 will send this to the address define don
this parameter. Any address between 00000 and 65535 is admitted.
60, 61, 62, 63, 64 and 65 - Clock settings
These parameters allow the adjustment of time: minute, hour, day of month, month, day of week and year of clock
respectively. Minute, hour , day of month, month and year are set directly, where year is a two digit value and days of
week has to be set from “1” to “7” as shown in table 15
