The ZTS Series is the building block of our transfer switch product line. This ruggedly built power contactor family of switches has been specifically designed for transfer switch duty with dependability, versatility and user friendliness of prime concern.

ZTS switches are available in open type construction

for switchboard installation or

NEMA enclosed to

the customer’s specifications. The power panel components, consisting of power switching contacts, drive mechanism and terminal lugs, are mounted on a specially formed panel. Logic devices including microprocessor control auxiliary time delays and special accessory equipment are assembled on the door for ease of maintenance and separation from the power section. They are connected with a numbered wiring harness equipped with a disconnect plug that allows isolation of the control panel for maintenance.

ZTS Series Method of Operation

When the normal source voltage fails or drops to a predetermined point (usually 80% of nominal), if required, a circuit is closed to start the engine generator set. When the emergency source reaches 90% of rated voltage and 95% of rated frequency, the drive solenoid is energized through the emergency coil control relay, causing the main contacts to disconnect the load from the normal source and connect it to the emergency source. After the drive solenoid has completed its electrical stroke and is seated, the emergency coil control relay opens to disconnect it. The transfer switch is now mechanically locked in the emergency position.

When normal voltage is restored to a predetermined point (usually 90% of nominal), the control voltage sensing energizes. The normal side coil relay closes, and after the drive solenoid has completed its electrical stroke and is seated, the coil control relay opens to disconnect it. The transfer switch is now mechanically locked in the normal position.

Drive Mechanism

All

GE Zenith ZTS switches employ the simple “over-

center” principle to achieve a mechanically locked position in either normal or emergency and

GE Zenith’s

high speed drive assures contact transfer in 100 ms or less. High contact pressure and positive mechanical lock allow for high withstand and closing ratings, far exceeding

UL requirements. All ZTS units are listed with

UL umbrella breaker, severe breaker and current

limiting fuse ratings.

ZTS Series Automatic Transfer Switches

Neutral Switching

The

GE Zenith ZTS Series is available in true four pole

designs for multi-source power systems that require neutral switching. The neutral contact is on the same shaft as the associated main contacts. This ensures positive operation, and avoids any possibility that the neutral contact will fail to open or close, as is possible when the neutral pole is an add-on accessory. The neutral contacts are identical to the main contacts, having the same current carrying and high withstand/ closing ratings as the mains. They are designed to break last and make first to reduce the possibility of transients while switching the neutral.

Safe Manual Operation

The

ZTS manual operator consists of a large, easy-to-use

handle that fits securely for manual operation during installation and maintenance or in an emergency.

The

ZTS may be provided with an operator inhibit

switch to disconnect the electrical drive prior to maintenance. Fully enclosed wrap-around arc covers shield the main contacts and mechanical components, preventing operator exposure during manual operation.

Transferring Large Motor or Highly Inductive Loads

Some loads, especially large motors, receive severe mechanical stress if power is trans-ferred out of phase while the motor is still rotating. Also, back

EMF gener-

ated by a motor may result in excess currents that can blow fuses or trip circuit breakers.

GE Zenith

offers four solutions to these problems:

PB-5066 •Page 2

1. Universal Motor Disconnect (UMD): This load

control disconnects a large motor via its control circuit for an adjustable period of time prior to transfer in either direction. For switching multiple motors, GE Zenith Accessory A62 disconnects the motors prior to transfer and brings them back on line sequentially.

2. Accessory R50: This is an in-phase monitor that compares the phase angle between both sources of power and prevents transfer until the two are approximately in phase (within a self adjusting range). GE Zenith’s high speed transfer action coupled with the MX series microprocessor control logic ensure closures at or near zero degree phase difference.

3. Series ZTSD: GE Zenith offers delayed transition switching on transfer switches rated 40 amperes and above – the GE Zenith ZTSD Series. This programmed center-off position allows for the full decay of rotating motors or transformer fields. It can also be used for load shedding of selected circuits or other appli-cations which require a means to disconnect the load from either source. Major UPS system manufacturers recommend delayed transition switches for proper restart sequencing of their systems.

4. Series ZTSCT: GE Zenith’s series of closed transition switches combine ZTSD operation during a source failure with a highly engineered control system that allows momentary paralleling (100 ms) of two acceptable sources, thereby limiting the impact of transfer on the load.

Microprocessor Controller

age 3 • PB-5066

LEDs are used in a recognizable line configuration for continuous monitoring of switch position. A new LCD display shows source availability, exercise time delay operation and system source condition. A new simplified adjustment is featured for voltage, frequency and time delay settings.

The control operates off a close differential 3 phase under-voltage sensing of source 1, factory standard setting 90% pickup, 80% dropout; underfrequency sensing of source 1 factory setting 95% pickup; voltage and frequency sensing of source 2, factory standard setting 90% pickup voltage, 95% pickup frequency. All factory settings are operator adjustable (see table below).

A test is standard (fast test/load/no load) to simulate source 1 failure - automatically bypassed should source 2 fail.

Switch Types

• Standard: Unless otherwise noted, the standard

switch with quick transfer will be supplied.

• Delayed Transition: When ordered as the ZTSD,

the delayed transition switch offers time delay during transfer from one position to the other. This is primarily for transfer of large motor or inductive loads.

• Closed Transition: When ordered as the ZTSCT,

the closed transition switch offers two basic modes of operation. During a failure of one source or an out of specification condition, the ZTSCT Model operates as a standard delayed transition switch (

ZTSD Model).

This sequence allows clear separation of an unreliable source from an available one.

• Bypass: When ordered as the ZBTS, the bypass

transition switch offers a draw-out mechanism, with electrical and mechanical interlocks for secure removal after load bypass. In this way the transfer switch and/or the control panel may be tested, isolated and removed for maintenance without load interruption.
