ComTroll 230, Remote Terminal Unit
The ComTroll 230 is designed for a complete and modular functionality for monitoring and
control of primary and secondary functions in the distribution network.
The rack-mounted system can control and monitor a wide range of objects such as pole-
mounted sectionalizers, breakers, earthing switches, relay protection, fault indicators, tap-
changers and more through its serial, digital and analog interface.
The analog inputs can be connected to different sensors reading values for power frequency,
active/reactive power, bus-bar voltage, load current and more.
Based on the RTU-30 Controller unit, ComTroll 230 offers both local- and remote control of
the connected equipment.
ComTroll 230 can be connected to a wide range of transceivers for different communication
solutions:
Radio
Fibre optics
Power Line
Leased Lines
Ethernet

With the extensible backplane solution, ComTroll 230 can be supplied in a 10.5” single frame
rack where up to three RTU-30/RTU-30i cards can be fitted. It can also be supplied in a full
19” single frame rack with space for up to eight RTU-30/RTU-30i cards.
RTU-30 is acting as a master for the additional RTU-30i cards. One RTU-30 can communicate
with 14 RTU-30i cards on the I2C-bus.

ComTroll 230 can be supplied as a –m version where the LED’s for status messages,
open/close button and the ModeSwitch (Remote/Off/Local) are removed.
Each RTU-30 /RTU-30i has dedicated OPEN and CLOSE outputs with accompanying open and
closed limit-switch inputs to ensure reliable operation.
Details about the RTU-30 /RTU-30i functions and options can be found in separate
document.

The ComTroll 230 Remote Terminal Unit can communicate with the central unit /SCADA on
different communication media. The most commonly used is low power radio and fiber-
optics, but the flexible communication platform can utilize almost any media using a
specified Transceiver module for the actual media used.
CRU-200 is a module comprising a modem and radio. Nortroll offers both VHF and UHF
radios with respectively frequency range 140-172 MHz and 406-460 MHz.
The ComTroll 230 with radio communication can be used as a repeater for other Nortroll
devices in the network.
Where other communication media is used, the radio is not mounted in the CRU-200. The
transceiver will in these cases normally be mounted outside the rack.

Power Supply
ComTroll 230 requires 12Vdc supply voltage with a battery backup. It can be solar charged in
configurations with up to three RTU cards. (With radio communication only).
SLC-200+ is the standard DC/DC regulator where external 12Vdc is available. This is also a
battery charger for the backup battery, both when external DC is connected and when a solar
panel is connected.
The SLC-200+ can be replaced with DC/DC-1, a regulator unit for input voltages between 18-
36 Vdc and 36-72 Vdc.
Connections
ComTroll 230 uses two different backplanes, 06310a and 06315a.
06310a covers the SLC-200+ (or DC-DC-1), the CRU-200 and one RTU-30 card.
Each additional RTU-30i card in a rack needs a separate backplane. The RTU-cards are tied
together on the Local Bus Bridge Cable, where also supply voltage is transferred to the next
unit.

Pin 1 is located in the upper left corner of J3.
F1: Connects the Low Battery signal from SLC-200+ to Digital Input 1 on the
NTM-20/25 Modem. Only used in repeaters. Default set open.
F2: Connects either External DC input or the Battery Input to the Analog
Input 4 on the first RTU-30 card. Battery voltage is monitored as the
default option. Ai_4 is setup to monitor voltages between 0V and 15Vdc.
F8: Activate / deactivate the termination of the twisted pair bus. Not
mounted as default.

Installing the TSU-25
Before powering the TSU-25, connect the antenna to the connector located on the front
panel. The GPS antenna needs to be located with a good clear 360 degree view of the sky.
The ideal location for the antenna is a roof-top. However, in practice the TSU-25 antenna
All events in a substation can be precisely time tagged by the use of
GPS Time Synchronization Unit, TSU-25.
The TSU25 utilizes the accurate time signal broadcasts from the GPS
satellite network.
The TSU-25 has an integrated GPS receiver that constantly tracks up to
8 satellites simultaneously to provide a highly accurate time reference.
A software clock on the RTU-30t card will be calibrated every minute to
time-stamp events that occur in the digital and analog inputs. The time
information will be sent together with the alarm/message to the
SCADA.
Up to 7 RTU-30t cards can be calibrated from one TSU-25.
The RTU-30t has the same functions and I/O package as RTU-30 and
RTU-30i.

Page 9
generally works well on a window-ledge or positioned in a window or wall. As a rule of
thumb, the better the view the antenna has of the sky, the better the signal locks and a good
continuous uninterrupted time signal is provided.
TSU-25 can only be used together with RTU-30t. When more than one RTU-30t card is
installed in the same rack, a Router Module (RTR-10) must be installed.
Running LED (green):
LED flash once every 10 seconds as long as the TSU-25 is powered and the software runs OK.
Sync-LED (yellow):
The LED flashes every second when the GPS-unit is active.
Status-LED (red):
When the TSU-25 does not have a valid time, the Status LED will flash once a second.
Normal operating condition:
The TSU will activate the GPS every 660s (11min) or 2500s (42min) dependent upon the
measured temperature. When the interval expires the GPS will be activated and the Sync-LED
will start flashing. The LED flashes until the clock is updated.
Independent of this update, the TSU-25 sends out a time-sync message on the backplane
bus. The RTU-30T cards that are placed on the same bus will receive this accurate time
information and update the software clock that runs constantly on each individual RTU-30t
card.
This will give an accuracy of +/- 10ms on the time information sent from the RTU upon an
event.
Different types of antennas are
available. The default antenna is a
3.3V active antenna, but other types
of antennas can be used.’
IMPORTANT:
Do NOT change any antenna settings
without consulting NORTROLL AS
first.
Wrong setting can cause permanent
damage to the GPS unit and the TSU-
25.

Page 10
Faulty operating condition:
If the GPS receiver is not able to establish contact with the satellites, the TSU-25 will see that
the attempt to download accurate time information failed.
When the next sync period expires, the Status-LED will start flashing together with the Sync-
LED. The Status-LED will stop flashing when the satellite contact is established again.
If for some reason the contact cannot be restored, or the TSU-25 is unable to update the
software clock on the RTU-30t the time information sent will drift (note! worst case) +/-7 sec
every 24-hour period.
ComTroll 230S
ComTroll 230S is a gateway that resides on the ComTroll Network and connects to Modbus
devices over EIA-232 or EIA-485. The controller module RTU-30s supports up to 14 Modbus
devices on a multi-drop EIA-485 network.
The RTU-30s can be installed in a ComTroll 230 rack where other RTU-30 versions (RTU-
30/RTU-30i/RTU-30t) are installed, and support all media available in the ComTroll Network
System.
