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.

Application Modes
Basic Applications
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
Application Mode: Util-Gen
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
Figure 2-1: Application mode - Util-Gen

Application Mode: Gen-Gen
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 controller
in Util-Gen application mode, which operates as Master controller
Figure 2-2: Application mode - Gen-Gen

Application Mode: Util-Util
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
•If “Connect to synchronous mains” parameter 8820 is enabled, the transfer between two utility
sources is allowed for the phase angle being in the phase angle range from 0 to value of “Max.
phase angle” parameter 8821.

Special Applications
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
Example Application: Transfer Delay (Util-Util)
The example shows two DTSC-200A (ATS 1 & ATS 2) which are feeding two loads (Load 1 & Load 2). Since
the two mains sources are always present, all stable delay timers are always expired. In case “Source 1” would
fail, both ATS would transfer both loads to “Source 2” immediately. In some transfer scenarios the loads can
have different priorities. In a hospital for example, “Load 1” could be the “Emergency” load and “Load 2” a
“Non-Emergency” load. In that case the system owner wants the “Emergency” loads to be transferred first, and
“Non-Emergency” loads to be transferred second. In such a scenario the “Transfer delay timers” become an im-
portant tool to prioritize the loads. See the following example:
Figure 2-4: Example application - transfer delay (Util-Util)
Example details:
•Assumption: ATS 1 transfer delay timers are configured to 5 seconds
•Assumption: ATS 2 transfer delay timers are configured to 10 seconds
•Source 1 and Source 2 are available and OK
•Now Source 1 fails
•After the transfer delay timer of ATS 1 has expired ( 5 seconds ), it will transfer Load 1 to Source 2
•After the transfer delay timer of ATS 2 has expired ( 10 seconds ), it will transfer Load 2 to Source 2
•Conclusion: Without the transfer delay timers, both ATS would transfer the load to Source 2 simultane-
ously

Example Application: External Permit Closed Transition
In some ATS applications the customer may want to use an additional “Sync-check relay” in combination with
the DTSC-200A for highest system security. Only if the external sync-check relay sends a “Synchronism detect-
ed” signal to the DTSC-200A, then the in-phase monitor in the DTSC-200A shall be activated.
The “Enable closed transition” LogicsManager is the ideal function to carry out this functionality.
Figure 2-5: Example application –external permit closed transition
Setup:
•Parameter “Ext. permit for cld. trans.” must be set to “On” to activate this feature
•Parameter “Transfer switch type” must be configured to “Closed”
•Wire the relay output of the external sync-check relay to a free discrete input on the DTSC-200A
•Configure the LogicsManager for “Enable closed transition” in such a way, that the discrete input you
intend to use is setup here
