WARNING
Read this entire manual and all other publications pertaining to the work to be performed before in-
stalling, operating, or servicing this equipment. Practice all plant and safety instructions and precau-
tions. Failure to follow instructions can cause personal injury and/or property damage.
The engine, turbine, or other type of prime mover should be equipped with an overspeed (overtempera-
ture, or overpressure, where applicable) shutdown device(s), that operates totally independently of the
prime mover control device(s) to protect against runaway or damage to the engine, turbine, or other
type of prime mover with possible personal injury or loss of life should the mechanical-hydraulic gov-
ernor(s) or electric control(s), the actuator(s), fuel control(s), the driving mechanism(s), the linkage(s),
or the controlled device(s) fail.
Any unauthorized modifications to or use of this equipment outside its specified mechanical, electrical,
or other operating limits may cause personal injury and/or property damage, including damage to the
equipment. Any such unauthorized modifications: (i) constitute "misuse" and/or "negligence" within
the meaning of the product warranty thereby excluding warranty coverage for any resulting damage,
and (ii) invalidate product certifications or listings.
CAUTION
To prevent damage to a control system that uses an alternator or battery-charging device, make sure
the charging device is turned off before disconnecting the battery from the system.
Electronic controls contain static-sensitive parts. Observe the following precautions to prevent dam-
age to these parts.
•Discharge body static before handling the control (with power to the control turned off, contact a
grounded surface and maintain contact while handling the control).
•Avoid all plastic, vinyl, and Styrofoam (except antistatic versions) around printed circuit boards.
•Do not touch the components or conductors on a printed circuit board with your hands or with
conductive devices.

Table 1-1: Manual - Overview
Intended Use The unit must only be operated for the uses described in this manual. The prerequisite for a proper
and safe operation of the product is correct transportation, storage, and installation as well as careful operation
and maintenance.
NOTE
This manual has been developed for a unit fitted with all available options. Inputs/outputs, functions,
configuration screens and other details described, which do not exist on your unit, may be ignored.
The present manual has been prepared to enable the installation and commissioning of the unit. On
account of the large variety of parameter settings, it is not possible to cover every possible combina-
tion. The manual is therefore only a guide. In case of incorrect entries or a total loss of functions, the
default settings can be taken from the enclosed list of parameters at the rear of this manual.

With this button the operator can manually initiate the LOAD TEST sequence. Once pushed he
must confirm over display whether he want to start the LOAD TEST with all its consequences.
NOTE
Initiating a LOAD TEST can cause a dead bus during switching the ATS control.
Confirming
No Confirming
With confirming over the return button, the manually LOAD TEST is initiated and the LED
LOAD TEST

If the LED LOAD TEST
18
is flashing the operator can abort the LOAD TEST by pushing the
LOAD TEST button again. With doing that he must confirm again to interrupt the LOAD TEST.
Confirming
No Confirming
If he confirms the abort of the load test the LED LOAD TEST

Operation Display
"Operation" display
The current operation state of the unit and the condition of the
sources are displayed during normal operation.
Operation state
The current operation state of the unit is indicated in the "Messages" section of the
screen. Refer to Appendix A: Messages on page 33 for a list of the possible operation
states.
Source condition
The current source condition is indicated in the "Operation" section of the screen. The
following source conditions are possible:
S1/2 Ok
Source 1/2 is considered as "OK", i.e., the voltage and frequency of Source 1/2 are with-
in the restore limits (refer to the Configuration Manual 37939 for more information).
S1/2 Fail
Source 1/2 is considered as "not OK", i.e., the voltage or frequency of Source 1/2 are not
within the restore limits (refer to the Configuration Manual 37939 for more information).
S1/2 Restore
Source 1/2 is considered as "OK", but the stable timer for the respective source has not
yet expired (refer to the Configuration Manual 37939 for more information).

Timer Display
"Timer" display
If a timer is active, it is indicated in the "Messages" section of
the screen and a numerical indication in the "Timer" section
counts down the remaining time before the timer expires.
Bypass timer
If a timer is currently active, it may be bypassed with the "Bypass" button.
Note: The Bypass feature is only possible if the LED over the Bypass button is
flashing.
This means with pushing the indicated timer expires immediately and the unit
proceeds with the next operation. Refer to Appendix A: Messages on page 33
for a list of the possible timers.
LogicsManager
Some parameters of the DTSC-200A are configured via the LogicsManager (refer to Configuration Manual
37940). A typical LogicsManager screen is shown in the following. You may configure a logical operation using
various command variables, signs, and logical operators to achieve the desired logical output.
LogicsManager Screen
For configuration of the LogicsManager use the softkeys dis-
played in the navigation button overview.
Leave current screen ("Escape" / "ESC")
By pressing this softkey character you exit and go to the previous screen. If the Escape
softkey is used to leave a LogicsManager configuration screen, any unconfirmed chang-
es made will not be stored.
Change option
By pressing these softkey characters plus and minus you may change the option of the
selected LogicsManager parameter upwards or downwards.
Confirm selection
By pressing this softkey character you confirm the configured option of the selected
LogicsManager parameter.
Select parameter
By pressing this softkey character you may select the LogicsManager parameter to be
configured. Each time this softkey character is pressed, the parameter will be advanced.

Select group of parameters
By pressing this softkey character you may select the next group of LogicsManager pa-
rameter if you are on an LMCV parameter. Each time this softkey character is pressed,
the next parameter group will be taken. With the last group it begins with the smallest
group again.

Application Modes
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The application mode may be configured in the unit (refer to the Configuration Manual 37940 for more infor-
mation). This is only possible in code level 2. The most important features and differences of the three applica-
tion modes are illustrated in the following section. A description of the functions that are possible during each
application mode can be found in the configuration manual (manual 37940).
Util-Util Application Mode
This application mode has the following characteristics:
•The ATS controller monitors two mains sources and transfers the load to the secondary source in
case the primary source fails
•The ATS controller operates as Master controller
Util-Gen Application Mode
This application mode has the following characteristics:
•The ATS controller monitors a mains sources and a generator source and transfers the load to the
generator source in case the mains source fails
•The ATS controller operates as Master controller
Gen-Gen Application Mode
This application mode has the following characteristics:
•The ATS controller monitors two generator sources and transfers the load to the other source in
case the regular source fails
•The ATS controller operates as Slave controller
•This application is not a stand-alone application and always combined with another ATS control-
ler in Util-Gen application mode, which operates as Master controller (refer to the Application
Manual 37942 for more information)
Engine operation special cases
In Util-Gen application mode and Gen-Gen application mode the ATS starts and stops an engine. Starting and
stopping is controlled by the state machine described above. However, in some rare situations the start/stop is af-
fected by the breaker state. These are
•If a breaker cannot be closed to a generator source (indicated by a corresponding alarm), then the engine
shall not run, it shall either not start or do a stop after cooldown
•If a breaker is connected to a generator source and cannot be opened (indicated by a corresponding alarm),
the engine shall continue to run.
•If a breaker closing to a generator source is inhibited, and the breaker is not already closed, the engine shall
not run or do a stop after cooldown.
