CAUTION!!!
Page 9
TS 830 TRANSFER SWITCH
Where transfer switches are supplied without power isolation transformers (PT1 & PT2) for ATS control logic it is essential that the orientation of phase conductors of the supply source be arranged such that the phase of highest potential with respect to ground is not connected to the power supply inputs to the controller (The A Phase for both supplies). Failure to do so will result in equipment damage. Per NEC Article 384-3 (f) “The B phase shall be that phase having the higher voltage to ground on a 3-phase, 4-wire delta connected systems.”
2.5. REMOTE START CONTACT FIELD WIRING
For applications using TSC 80e controllers, as a minimum, the remote engine start control field wiring shall conform to the local regulatory authority on electrical installations. Field wiring of a remote start contact from a transfer switch to a control panel should conform to the following guidelines to avoid possible controller malfunction and/or damage.
3.5.1. Minimum #14 AWG (2.5mm2) wire size shall be used for distances up to 500ft
(150m)1). For distances exceeding 500 ft. (150m) consult Thomson Power Systems.
3.5.2. Remote start contact wires should be run in a separate conduit.
3.5.3. Avoid wiring near AC power cables to prevent pick-up of induced voltages.
3.5.4. An interposing relay may be required if field-wiring distance is excessively
long (i.e. greater than 500 feet (150m) and/or if a remote contact has a resistance of greater than 5.0 ohms.
3.5.5. The remote start contact must be voltage free (i.e. dry contact). The use of a
“powered” contact will damage the transfer controller.
2.6. DIELECTRIC TESTING
Do not perform any high voltage dielectric testing on the transfer switch with the controller connected into the circuit, as serious damage will occur to the controller. All AC control fuses and/or control circuit breakers or control circuit isolation plugs connected to the controller must be removed if high voltage dielectric testing is performed on the transfer switch.
2.7. INSTALLATION OF OPEN TYPE TRANSFER SWITCHES
Please contact Thomson Power Systems for additional information.

TS 830 TRANSFER SWITCH
3. GENERAL DESCRIPTION
Thomson Power Syste ms TS 830 series of Automatic Transfer Switches employ two mechanically interlocked enclosed contact power switching units and a microprocessor based controller to automatically transfer system load to a generator supply in the event of a utility supply failure. System load is then automatically re-transferred back to the utility supply following restoration of the utility power source to within normal operating limits. Transfer switches with MEC 2, MEC 20 or MEC 310 controllers installed have integral engine-genset auto start control & monitoring features and therefore these applications do not require an engine-mounted auto start control panel.
The standard TS 830 series Automatic Transfer Switch is rated for 100% system load and does not require upstream over current protection. Refer to Section 6 of this manual for detailed information on over current protection.
The TS 830 series transfer switch may be supplied with type TSC 80e, TSC 800, MEC 310 or MEC 20 controllers as specified at equipment order. All controllers are microprocessor based which provides all necessary control functions for fully automatic operation. The controllers are mounted on the door of the transfer switch enclosure and operating status is shown via LED lights and/or LCD display dependent upon controller type. For further information on the controller utilized, refer to separate instruction manuals.
The power switching devices used for the Utility and Generator sources are operated by an electrically driven motor mechanism in the transfer switch. The transfer switch motor utilizes the power from the source to which the electrical load is being transferred. The mechanism provides a positive mechanical interlock to prevent both power switching units from being closed at the same time, which allows an interrupted “break-before-make” transfer sequence.
Note: For the purpose of this manual, the following standard nomenclature is utilized:
Utility: to indicate the source of primary power Generator: to indicate the source of standby power Power switching device: to indicate the transfer switch power switching device
3.1. PRODUCT MODEL CODE
The type of TS 830 series transfer switch supplied is identified by way of a 21 digit product code which appears on the equipment rating plate (MODEL) on the door of the transfer switch, and on the transfer switch drawings. The model code structure and definitions are as follows:

TS 830 TRANSFER SWITCH
4. GENERAL THEORY OF OPERATION
4.1. STANDARD AUTOMATIC TRANSFER SWITCH
4.1.1. NORMAL OPERATION
When utility supply voltage drops below a preset nominal value (adjustable from 70% to 100% of nominal) on any phase, an engine start delay circuit will be initiated and the transfer to utility supply signal will be removed (i.e. contact opening). Following expiry of the engine start delay period (adjustable from 0 to 60 sec.) an engine start signal (contact closure) will be given.
Once the engine starts, the transfer switch controller will monitor the generator voltage and frequency levels. Once the generator voltage and frequency rises above preset values (adjustable from 70% to 95% of nominal), the engine warmup timer will be initiated. Once the warmup timer expires (adjustable from 0 to 60 sec.), the Transfer to Generator Supply signal (contact closure) will be given to the transfer switch mechanism. The load will then transfer from the utility supply to the generator supply via the motor driven mechanism.
The generator will continue to supply the load until the utility supply has returned. The retransfer sequence is completed as follows: when the utility supply voltage is restored to above the preset values (adjustable from 70% to 95% of nominal) on all phases, a transfer return delay circuit will be initiated. Following expiry of the Utility Return Timer (adjustable from 0 to 30 min.), the Transfer to Generator Supply signal will be removed (contact opening), and then the Transfer to Utility Supply signal (contact closure) will be given to the transfer switch mechanism. The load will then retransfer the load from the generator supply back to the utility supply. Note: For transfer switches with TSC 80e/800 controllers, a neutral delay timer circuit will delay the transfer sequence in the neutral position (i.e. both power switching devices open) until the neutral time delay period expires (adjustable from 0 to 60 sec.).
An engine cooldown timer circuit will be initiated once the load is transferred from the generator supply. Following expiry of the cooldown delay period (adjustable from 0 to 30 min.), the engine start signal will be removed (contact opening) to initiate stopping of the generator set. Note: For transfer switches with MEC 2/20, MEC 310 controllers, engine start signal is internal to the controller.

Page 13
TS 830 TRANSFER SWITCH
4.1.2. OVER CURRENT TRIP (TSC 80e/TSC 800 CONTROLLERS)
Should the utility power switching device trip open due to an over current condition, TSC 80e or TSC 800 transfer controller will initiate an engine start signal and will permit transfer of the load to the generator supply. The utility source will be locked out and the load will remain on the generator supply until the TSC 80e/TSC 800 alarm signal is manually reset. Refer to the TSC 80e & TSC 800 Instruction Manuals for further details on Transfer Fail operation.
Should the generator power switching device trip open due to an over current condition, TSC 80E/TSC 800 transfer controller will initiate transfer of the load to the utility supply. The generator source will be locked out and the load will remain on the utility supply until the TSC 80E/TSC 800 alarm signal is manually reset.
4.1.3. OVER CURRENT TRIP (MEC 2/MEC 20/MEC 310 CONTROLLERS)
Should the utility power switching device trip open due to an overcurrent condition, the generator will not automatically start and transfer on load. The generator must be started and transferred on load manually. Should the generator power switching device trip open due to an overcurrent condition, the generator will shutdown and the load will automatically return to the utility supply if its voltage is normal. Note: for automatic transfer to utility, the transfer switch must be factory ordered with a “gen breaker tripped” auxiliary contact inside the generator power switching device and must be wired to the gen set controllers shutdown alarm circuits. Refer to the Gen Set controller instruction manual for further details on manual operation or shutdown-reset operation.
4.2. TEST MODES
The transfer switch may be tested utilizing the controller pushbuttons or optional test switch. A simulated utility power failure condition will be activated when the test mode is selected. The transfer switch will operate as per a normal utility power fail condition. The transfer switch will remain on generator supply until the test mode is terminated. It will then immediately transfer back to the utility supply and then continue to operate the generator set for its cooldown period then stop. Note: The transfer switch will automatically return to the utility supply (if within nominal limits) if the generator set fails while in the test mode.

TS 830 TRANSFER SWITCH
5. OVER CURRENT PROTECTION
Thomson Power Systems TS 830 series of Automatic Transfer Switches are supplied standard with integral over current protection.
The type of over current protection utilized is dependent upon ATS amperage size and optional features specified. For transfer switches rated 125A through 800A, over current protection is non­adjustable thermal-magnetic type trip units. For transfer switches rated 1000A through 1600A over current protection is adjustable electronic type with long time & instantaneous trip unit elements with optional ground fault protection elements.
Note: For models of transfer switch with adjustable integral over current protection trip units, the over current protection must be set prior to operation. The equipment will be shipped from the factory with a long-time current setting of 100% (of the equipment rating) and maximum instantaneous/short-time/ground fault (if supplied) current and time delay settings.
WARNING! Do Not Energize this equipment until device settings have been verified to ensure proper system protection & coordination. Failure to do so may result in equipment failure.
6. GENERAL NOTES ON SERVICING ATS MECHANISM
DANGER!!!!
Arc Flash and Shock Hazard. Will cause severe injury or death.
Do not open equipment until ALL power sources are disconnected
This equipment must be installed and serviced only by qualified electrical personnel utilizing safe work practices and appropriate Personal Protective Equipment (PPE). Failure to do so may cause personal injury or death
When performing any service work on the transfer mechanism, it is imperative that the following be observed:
7.1. To maintain mechanical integrity, ensure that:
PM059 REV 9 14/01/16 10 Thomson Power Systems
Page 15
TS 830 TRANSFER SWITCH
All limit switches linkages are correctly adjusted to provide full travel of the power
switching device toggles without exerting unnecessary forces associated with excessive travel. Ensure that power switching device travel far enough to reset any internal trip unit (it is more important for the toggle to go fully in the "off" direction, than in the "on" direction).
Mechanical interlocking is correct when one power switching opens well before
the other should close.
All fasteners are adequately tightened. The operating linkages are not damaged or bent, and that all bearing points
operate freely.
7.2. To maintain electrical integrity, ensure that: All electrical connections, especially power connections, are clean and adequately
tightened. Corroded or loose power connections will cause destructive heating, and may cause premature tripping.
All insulating devices are in place and in good condition. No moisture or other contamination is present. Electrical conductors are adequately secured away from moving parts. On HS style transfer switch mechanisms, check nylock nuts on bolt pivot points.
Operation arms should move freely without excessive play.
7.3. To maintain operational integrity, ensure that:
All control devices are in good condition and correctly calibrated. All control devices are adequately secured in their plug-in fixtures.
Only qualified personnel should undertake service work. Failure to correctly maintain an automatic transfer switch may present a hazard to life and equipment. Full operational testing must be done prior to placing a transfer switch in service subsequent to any maintenance or repair. Any service work involving electrical components requires high­potential testing to ensure that required insulation levels have been maintained.
7. TRANSFER SWITCH MECHANISM – 125 - 800 Amp (S Style)
The transfer mechanism consists primarily of the transfer gear motor, a drive hub assembly, and two power switching device operating arms. The reversible transfer gear motor drives the drive hub assembly, which in turn moves the power switching device operating arms. The power switching device toggles are set inside the operating arm slots and are moved by them. There are two limit switches, which are contacted by the operating arms (one for each power switching device), which disconnect the transfer motor power supply when the power switching devices have attained full travel. Should limit switch adjustment be required, it is advisable to consult Thomson Power Systems for further information.
PM059 REV 9 14/01/16 11 Thomson Power Systems
Page 16
TS 830 TRANSFER SWITCH
The transfer switch mechanism has three possible positions: a) Utility power switching device closed and generator power switching device open; b) Generator power switching device closed and utility power switching device open;
c) Both utility and generator power switching devices open, but NEVER both utility and
generator power switching devices closed at the same time.
7.1. MANUAL OPERATION
DANGER!!!!
Arc Flash and Shock Hazard. Will cause severe injury or death.
Do not open equipment until ALL power sources are disconnected
This equipment must be installed and serviced only by qualified electrical personnel utilizing safe work practices and appropriate Personal Protective Equipment (PPE). Failure to do so may cause personal injury or death
Isolate the transfer switch from all sources of supply before opening the enclosure for manual operation. With all sources of power de-energized to the transfer switch, the control circuit isolation plug can be unplugged to prevent subsequent operation. The control circuit isolation plug is located on the inner side of the transfer switch enclosure door. To operate manually, insert the operating handle into the square hole on the front of the mechanism and rotate to the desired position. Remove the operating handle once operation is complete and re-insert into the handle holder on the left-hand side of the transfer switch mechanism. Automatic operation may be regained by replacing the control circuit isolation plug. With all sources of power de-energized to the transfer switch, the control circuit isolation plug can be re-connected. The drive system will operate the transfer switch to the required position. (See manual operation instruction on front of transfer switch mechanism.)

TS 830 TRANSFER SWITCH
8. TRANSFER SWITCH MECHANISM – 1000A- 1600 Amp (T Style)
The transfer mechanism consists primarily of the transfer motor, a hub assembly, two operating rods and two power switching device operating yokes.
The reversible transfer motor drives the hub assembly, which in turn moves the operating rods that are connected to the power switching device operating yokes. The power switching device toggles are set inside the yokes and are moved by them. There are two limit switches, which are contacted by the operating yokes (one for each direction of travel), which disconnect the transfer motor power supply when the power switching devices have attained full travel. The adjuster screws located on the yoke determines the operating point of these limit switches. Should adjustment be required, it is advisable to consult Thomson Power Systems for further information. The transfer switch mechanism has three possible positions: a) Utility power switching device closed and generator power switching device open; b) Generator power switching device closed and utility power switching device open;
d) Both utility and generator power switching devices open, but NEVER both utility and
generator power switching devices closed at the same time.
8.1. MANUAL OPERATION
(See CAUTION! on Page #2)
Isolate the transfer switch from all sources of supply before opening the enclosure for manual operation. With all sources of power de-energized to the transfer switch, the control circuit isolation plug (PL12) can be unplugged to prevent subsequent operation.
To operate manually, pull the release plunger and operate the handle in the desired direction.
Automatic operation may be regained by replacing the isolation plug. With all sources of power de-energized to the transfer switch, the control circuit isolation plug (PL12) can be re­connected. The drive system is self-engaging and will operate the transfer switch to the required position. (See manual operation instruction on front of transfer switch mechanism.)
