2.4.1. AC VOLTAGE SENSING INPUT

The TSC 80e can accept direct AC voltage sensing inputs on the generator and utility

supplies from 120-600VAC (nominal). Note: Direct input voltage sensing can only be

used when the system utilizes a 3 phase, 4 wire distribution system which has the

neutral conductor solidly grounded. For 3 phase, 3 wire systems (i.e. no neutral) or

high voltage systems, potential transformers must be used. Refer to FIGURE 3 for

voltage sensing connections.

2.4.2. AC CONTROL POWER INPUT

The TSC 80e is factory supplied for 120VAC (nominal) control power input voltage.

Independent AC control power is required from both utility and generator supplies. AC

control power is utilized for internal TSC 80e control circuits and external control

device loads. The TSC 80e requires approximately 6 VA power for internal control

circuits. The maximum external load is limited by output contact ratings (i.e. 10A

resistive, 120VAC). Total AC control power requirements for each supply must be

determined by adding both internal and external load requirements.

2.4.3. OUTPUTS

The TSC 80e provides the following types of output circuits:

Engine Start Contact Isolated Form B contact (10A, 120VAC Resistive)

Transfer to Utility Output 120VAC, 10A (Resistive) powered output contact

Transfer to Generator Output 120VAC, 10A (Resistive) powered output contact

The TSC 80e provides the following additional output circuits:

Programmable Output Contact #1

Programmable Output Contact #2

Programmable Output Contact #3

Programmable Output Contact #4

Programmable Output Contact #5

Isolated Form C contact (10A, 120VAC/250VAC Resistive)

Interposing relays are required between the TSC 80e outputs and the end device if

loads exceed the output current rating.

PM091 Rev 1 09/02/27 Thomson Technology

TSC 80e TRANSFER SWITCH CONTROLLER

3. OPERATING INSTRUCTIONS

To operate the TSC 80e controller and associated transfer switch using the front faceplate

pushbuttons, refer to the following detailed operating instruction sub-section descriptions.

3.1. AUTOMATIC SEQUENCE OF OPERATION

3.1.1. NORMAL OPERATION

Under normal operating conditions, the transfer switch operates automatically during a

failure and restoration of utility power and does not require operator intervention.

When utility supply voltage drops below a preset nominal value (70 - 95% of rated

adjustable) on any one phase, an engine start delay 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 (0 - 60 sec. adjustable) an engine start signal will be given

(contact closure, relay drops out to initiate start sequence).

Once the engine starts, the transfer switch controller will monitor the generators

voltage and frequency levels. When the generator voltage and frequency rises above

preset values (70 - 95% nominal adjustable) the Engine Warm-up timer will be

initiated. After the Engine Warm-up timer expires (0-60 sec. Adjustable), 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 motor driven mechanism (Neutral Delay is bypassed on utility failure detection).

The generator will continue to supply the load until the utility supply has returned and

the retransfer sequence is completed as follows: When the utility supply voltage is

restored to above the present values (70 - 95% of rated adjustable) on all phases, a

transfer return delay circuit will be initiated. Following expiry of the utility transfer

return timer (0 - 30 min. adjustable), the transfer to generator supply signal will be

removed (contact opening), then the transfer to utility supply signal (contact closure)

will be given to the transfer switch mechanism. The load will then be transferred from

the generator supply back to the utility supply. During the utility re-transfer sequence a

neutral positioning delay circuit will cause the transfer mechanism to pause in the

“neutral position (i.e. with both transfer power switching devices open) for the duration

of the neutral delay timer (0-30 seconds adjustable) setting. Once the neutral delay

expires, the re-transfer sequence will be completed.

PM091 Rev 1 09/02/27 Thomson Technology

TSC 80e TRANSFER SWITCH CONTROLLER

An engine cooldown timer circuit will be initiated once the load is transferred from the

generator supply. Following expiry of the cooldown delay period (0 - 30 min.

adjustable) the engine start signal will be removed (contact opening) to initiate

stopping of the generator set.

3.1.2. ABNORMAL OPERATION

3.1.2.1.TEST CONDITION

A test pushbutton on the transfer switch shall signal a simulated utility power

fail signal to the transfer switch controller. The transfer switch shall operate as

per a normal utility power fail condition. The neutral delay circuit logic will be

active during transfer to and from the generator supply (i.e. when both sources

of power are available).

The transfer switch shall remain on generator supply until the test mode is

terminated. It will then retransfer back to the utility supply following expiry of

the transfer return timer and then continue to operate the generator set for its

cooldown period then stop.

3.1.2.2.GENERATOR FAILURE ON LOAD

Should the generator set fail while on load, the transfer switch shall retransfer

the load back to the utility supply if within nominal limits. The utility return and

neutral delay timers will be bypassed in this condition.

NOTE

This operating condition shall apply to a normal utility failure as

well as any test condition.

3.1.2.3.TRANSFER SWITCH FAIL ALARM LOGIC

The TSC 80e controller contains logic to detect a transfer mechanism failure.

Should a failure be detected, a forced transfer to the alternate supply will be initiated. Detailed logic operation is as follows:

NOTE

Disabling of the “TRANSFER SWITCH FAIL” feature is possible

by selecting the “Disconnected” position on “Service Entrance

Models” or by a closure between terminals 38 & 42 on the TSC

80e. In these situations the TSC 80e controller will not verify

that the transfer mechanism has operated correctly to provide

power to the load bus.

PM091 Rev 1 09/02/27 Thomson Technology

TSC 80e TRANSFER SWITCH CONTROLLER

3.1.2.4.TRANSFER FAIL DETECTION-NORMAL STEADY STATE CONDITION (NON-TRANSFERRING)

i. Limit Switch Failure (i.e. open contact) - Transfer Fail Alarm is initiated

(Load on Source Flashing LED) after a 9-second delay, and then a forced

transfer to the alternate source is initiated, if valid and available. Re-

transfer back to the original source will not occur until the Transfer Fail

alarm condition is reset. Refer to item 3.3 for Transfer Fail Fault Reset

details.

ii. Loss of Load Voltage (<80VAC) (i.e. Power switching device Tripped or

Failed to Close/Conduct Condition) - Transfer Fail Alarm is initiated (Load

Source Flashing LED) after a 5-second delay, then a forced transfer to the

alternate source is initiated, if valid and available. Re-transfer back to the

original source will not occur until the Transfer Fail alarm condition is reset.

Refer to item 3.3 for Transfer Fail Fault Reset details.

iii. Limit Switch Failure & Loss of Load Voltage <80VAC - Transfer Fail Alarm

is initiated (Load Source Flashing LED) after an 11-second delay, then a

forced transfer to the alternate source is initiated, if valid and available. Re-

transfer back to the original source will not occur until the Transfer Fail

alarm condition is reset. Refer to item 3.3 for Transfer Fail Fault Reset

details.

3.1.2.5.TRANSFER FAIL DETECTION - TRANSFERRING CONDITION

Transfer Source to Neutral – “NEUTRAL POSITION TIME” (10 seconds-

adjustable) starts timing as soon as a transfer to the alternate source is

initiated. During this period the ATS motor is energized and moves the

mechanism from the original source to neutral. The power to the motor will be

de-energized when either the “NEUTRAL POSITION TIME” times out or the

load voltage drops below 80VAC on all phases (whichever occurs first). Once

the ATS motor is de-energized, the Neutral Delay timer starts timing (all other

timers are halted while neutral delay timer is running). Once the Neutral Delay

timer expires the motor is re-energized to continue the transfer (see below).

Note: Normally the load voltage will typically drop below the 80VAC setpoint

within 1 second when the source power-switching device opens and therefore

the “NEUTRAL POSITION TIME” never times out. The default setting of this

timer (10 seconds) is intentionally set long so that it will not pre-maturely stop

the ATS mechanism.

PM091 Rev 1 09/02/27 Thomson Technology

TSC 80e TRANSFER SWITCH CONTROLLER

Transfer Neutral to Source– “Find Neutral/Source Timer” starts timing as soon

as the Neutral Delay timer times out. During this period the motor is energized

and moves the mechanism from the neutral to the alternate source. The power

to the ATS motor will be de-energized when either the mechanism’s limit switch

activates (i.e. external logic to the TSC 80e) or the “Find Neutral/Source Timer”

times out (whichever occurs first). Note: During the above 2 sequences the

“Transfer Fail Alarm” logic is inhibited. Once the 2 sequences have been

completed, the “Transfer Fail Alarm” logic will be re-enabled and will only be

triggered if conditions as described in item A (Normal Steady State Condition)

are sensed (limit switch and/or loss of load voltage).

For example, if the ATS mechanism fails to move (i.e. due to broken rod, motor

failure or manual release plunger not re-engaged), the total time before a

transfer fail will be initiated is 31 seconds (i.e. Find Neutral/Source Timer” (10

sec) + Find Neutral/Source Timer” (10 sec) + Limit Switch Failure & Loss of

Load Voltage <80VAC (11 sec) = 31 seconds Total).

3.1.2.6.SERVICE ENTRANCE ATS

For Service Entrance Rated transfer switch applications, the transfer switch

control logic will include external wiring from the TSC 80e to signal the transfer

switch mechanism to move to the “Service Disconnected” position. In this mode

the TSC 80e transfer control outputs and Transfer Fail feature is disabled.

3.2. TEST MODES

3.2.1. UTILITY POWER FAIL SIMULATION (LOAD TEST)

To simulate a utility power failure condition, press and hold the “UTILITY

POWER FAIL SIMULATE” pushbutton on the Lexan faceplate until the LED

light above the pushbutton changes state, approximately 5 seconds. Once the

mode is initiated, the engine start will be activated, when the engine

accelerates to nominal voltage and frequency levels, the load will automatically

transfer to the generator supply. To terminate the Utility Power Fail Test Mode,

the Test pushbutton must be held until the LED light above the pushbutton

changes state, approximately 5 seconds. When the pushbutton is released the

LED light will go out and, the load will re-transfer back to the utility supply

following expiry of the Utility Return delay timer.

PM091 Rev 1 09/02/27 Thomson Technology

TSC 80e TRANSFER SWITCH CONTROLLER

NOTE

The load will automatically re-transfer to the utility supply should

the generator fail while on load and the utility supply is within

applicable limits.

3.2.2. AUTOMATIC PLANT EXERCISE TEST

The TSC 80e controller provides both pre-programmed and user

programmable automatic plant exercise programs. Refer to SECTION 4.6.3 for

further details on the programmable “Automatic Exercise”. The generator set

will be exercised either “on or off” load dependent upon the controller software

program setting (refer to SECTION 4.6.5.11).

To initiate an automatic plant exercise mode cycle, press and hold the AUTO

GEN EXERCISE TEST pushbutton on the Lexan faceplate until the LED light

above the pushbutton changes state, approximately 5 seconds. Once the

mode is initiated, the engine will immediately start and transfer on load (i.e. if

configured for On Load Test, “factory default is off load test”) once nominal

voltage and frequency levels have been obtained. The engine will remain

operating on load until the plant exercise time delay period of 30 minutes

expires, then the load will re-transfer back to the utility supply. The system will

then be automatically re-tested at the programmed “Automatic Exercise”

Start/Stop/Day/Time.

NOTES

1. The load will automatically re-transfer to the utility supply

should the generator fail while in the test mode.

2. To bypass the exercise run period, press and hold the

Exercise pushbutton on for 5 seconds until the LED remains on.

The Generator Exercise LED light will operate as follows:

 LED ON - Exercise Timer is initiated, the programmable 7-14-21-28 day

timer is active and the generator is in the off state.

 LED FLASHING - Exercise Timer is initiated, the programmable minute

run timer is active and the generator is running on loads.

 LED OFF - Exercise Timer is not initiated and the programmable timer

is not active.

To terminate the Auto Generator Exercise Mode, the Exercise pushbutton must

be held on for approximately 5 seconds until the LED light above the

PM091 Rev 1 09/02/27 Thomson Technology

TSC 80e TRANSFER SWITCH CONTROLLER

pushbutton starts flashing. When the pushbutton is released, the LED light will

go out and the system will return to normal operation.

NOTE

To enable the Auto Exercise mode without initiating an

immediate exercise test, operator must first place the gen set

engine control to off, then press the Exercise button once to

initiate the test feature, then press it a second time to cancel

the immediate test. The gen set engine control can then be

returned back to the Automatic position, no starting of the gen

set or transferring of the facility loads should occur.

3.2.3. FOUR FUNCTION REMOTE TEST (FTS4 OPTION)

The function of the Four Position Test Switch Input is to allow operators to select various

operating scenarios for test or maintenance purposes, in addition to the use of the faceplate

mounted pushbuttons.

NOTE: When an external FTS4 switch is used, the TSC 80e operation as selected from the

faceplate pushbuttons will be overridden.

OFF: Disables the engine start output from the transfer switch. If the

primary source is available, and within normal limits, the TSC 80e

will initiate a transfer to the primary source. The transfer switch will

not automatically transfer to the secondary (alternate) source should

the primary source fail.

AUTO: All automatic functions are enabled.

ENGINE START: (No load test) An engine start signal will be initiated and will remain

on until the FTS4 is placed in another position. The engine will start

if the engine’s auto start controller is in the ”Auto” mode. If the

primary source fails in this mode, and the secondary source is within

parameters, the TSC 80e will initiate a transfer to the secondary

source. When the Engine Start input is removed, the generator will

continue to run if it has not operated for a time equal to or greater

than the minimum run time (i.e. based on the Engine Cooldown

Timer setting).

TEST: (Full load test) A primary source failure is simulated and an engine

3.2.4. REMOTE TEST

To activate a remote load test, a remotely controlled contact is to be closed between

terminal #38 and terminal #44. When the contact closes, an engine start will be

activated, once the engine accelerates to nominal voltage & frequency levels and the

Warm Up Timer expires, the load will be automatically transfer to the generator supply.

When the remote contact is opened, the load will re-transfer back to the utility supply

start signal will be initiated. When the secondary source is within

normal limits, the TSC 80e will initiate a transfer to the secondary

source. The system will remain in this state until the FTS4 is placed

in another position or the secondary supply fails. Upon a secondary

supply failure, if the primary supply is available, the TSC 80e will

initiate a transfer to the primary supply. The Engine Cooldown time

sequence will be initiated when the test mode is terminated.

following expiry of the Utility Return delay timer. The Engine Cooldown time sequence

will be initiated when the test mode is terminated.

The load will automatically re-transfer to the utility supply should

the generator fail while on load.

3.3. TRANSFER FAIL FAULT RESET

To reset a Transfer Fail condition, simultaneously press and hold both the Up & Down

arrow pushbuttons on the Lexan faceplate for approximately 5 seconds, the LEDs

above the buttons will commence oscillating after 5 seconds indicating the reset has

been achieved. A flashing LED above the associate source contact on the face of the

TSC 80e Lexan annunciates a Transfer Fail alarm condition. This event will cause the

TSC 80e to force a transfer of the facility loads to the alternate source, after the fault is

reset; the load will automatically retransfer back to the preferred/selected source if

within normal limits (a slight delay is typical before re-transfer commences).

NOTE:

This sub-menu item cannot be accessed with user or

Master Password.

4.6.5. SYSTEM CONFIG

4.6.5.1.System Voltage

Twelve system voltage setpoints can be programmed in software for the TSC

80e controller (i.e. 120, 128, 208, 220, 230, 240, 380, 400, 440, 460, 480, 575,

600V). The system voltages are typical system Phase-to-Phase nominal

voltages.

NOTES

1. For 3 phase 3 wire or high voltage applications utilizing

potential transformers with 120V or 128V nominal secondary

voltage, the controller must be programmed with 120V or 128V

setting. Terminal #43 input is ignored in this application with

the TSC 80e.

PM091 Rev 1 09/02/27 Thomson Technology

TSC 80e TRANSFER SWITCH CONTROLLER

3. For nominal system voltages that are not provided by specific

software values, refer to Section 4.6.5.2

When a system voltage is selected, the TSC 80e’s utility and generator under

voltage setpoint percentage setting will be automatically programmed to

correspond to the sensing input voltage (e.g. with a 600V system voltage

selected, and a 80% under voltage software setting, the under voltage sensor

will be activated below 540VAC).

PM091 Rev 1 09/02/27 Thomson Technology

TSC 80e TRANSFER SWITCH CONTROLLER

4.6.5.2.TSC 80e UNDER VOLTAGE SETPOINTS WITH NON-STANDARD SYSTEM VOLTAGES

When the Transfer Switch & TSC 80e transfer controller is applied to non-

standard system voltages, the TSC 80e under voltage software setting

percentages will not correspond to the correct voltage drop out setting.

To obtain the correct drop-out voltages using non-standard system voltages,

the TSC 80e software under voltage setpoints need to have an offset

percentage adjustment with the corresponding voltage software settings.

For non-standard system voltages, the following formula can be used:

A) Desired Drop-out Voltage= Drop-out % x System Voltage

B) TSC 80e UNDER VOLTAGE Setting = (Desired Drop-out voltage x 100)

TSC 80e System Voltage Setting

Example: for 200V system, 85% of 200V= .85 x 200V= 170V

TSC 80e software Setting = (170 x 100)

208

TSC 80e Software Setting = 82%

NOTE

The TSC 80e System Voltage Setting in Software must be set

to be equal to the nominal system voltage level or the next

highest setting available (e.g. 200V system voltage must use

208V jumper setting).

4.6.5.3.PT Ratio

The TSC 80e controller can be programmed in software to display correct

Utility or Generator system line voltage when external Potential Transformers

are utilized on the voltage sensing inputs. Potential Transformers are typically

applied when 3 phase 3 wire system voltage are only available. This menu has

a programmable range of PT ratios from 1.0 to 25.0. Example: for use with

480:120 potential transformers, program ratio of 4.0. To offset minor output

voltage variances of potential transformers used, PT ratio can be programmed

slightly higher or lower using the “tenths” digit. TSC 80e controllers utilizing

direct connected voltage sensing (i.e. without PTs) are to be programmed as

setting “1.0”.

PM091 Rev 1 09/02/27 Thomson Technology

TSC 80e TRANSFER SWITCH CONTROLLER

NOTE

The PT Ratio setting affects the displayed Utility & Generator

voltages when the SYSTEM VOLTAGE is set for 120V or 128V.

The PT ratio setting has no affect with any other system voltage

settings.

4.6.5.4.System Frequency

The TSC 80e controller can be programmed in software for 2 system

frequencies 50Hz or 60Hz.

When a system frequency is programmed, the TSC 80e’s generator frequency

setpoint percentage setting will be automatically programmed to correspond to

the sensing input frequency (e.g. with a 60Hz system frequency, and a 90%

under frequency potentiometer setting, the under frequency sensor will be

activated below 54.0 Hz).

4.6.5.5.System Phases

The TSC 80e controller can be programmed in software for two types system

Phases, single phase or 3 phase. Phase C voltage sensing input is ignored in

the single-phase mode.

4.6.5.6. 3 Wire Delta

This is a status menu only to indicate if the controller is currently configured for

3 wire operation. The status will indicate “YES” when the SYSTEM VOLTAGE

Setting is programmed to = 120V or 128V which enables the 3 Wire Delta

system operation.

4.6.5.7.LDC Transfer

The TSC 80e controller can be programmed in software to perform a Load

Disconnect signal operation prior to and following a load transfer. To enable the

LDC signal, program as YES. Refer to sections 5.4.9.7 & 5.4.9.8 for

programming the LDC time delay functions and section 5.4.10 for assigning the

desired type of output contact signal.

This is a status menu only to indicate if the controller is currently set to

Automatically test the generator set as initiated by the front faceplate AUTO

EXERCISE pushbutton. This menu item is not programmable.

4.6.5.10.Dual Event Test

The TSC 80e controller can be programmed in software to select a Dual event

test (i.e. The first programmed Plant exercise event will perform a Load test,

then the second programmed Plant exercise event will perform, a no-load test

will be performed). To select a Dual Event Test, program as YES.

4.6.5.11.Xfr on Load Test

The TSC 80e controller can be programmed in software to select the desired

Plant Exercise testing mode (i.e. load test with transfer or no-load test) for the

programmable exercise function or for a remotely initiated Test mode. To

select a Xfer on Load test, program as YES.

NOTES

1. The No-Load Test mode is the factory default setting.

2. Should utility power fail during a no-load test operation, the

load will automatically transfer to the generator and will re-

transfer back when utility power is restored to within normal

conditions. The engine will continue to run until the 30 minute

exercise time delay period expires.

4.6.7. UTILITY VOLTAGE SETPOINTS

The TSC 80e controller provides 3-phase under voltage sensing on the utility supply.

Each sensor is individually programmable for pickup and dropout voltage setpoints (i.e.

adjustable hysteresis). To program the voltage sensing features, refer to the following

descriptions:

4.6.7.1.Utility Under Voltage Drop Out

Set to the desired utility under voltage setpoint at which the internal voltage

sensor drops out (i.e. the sensor de-energizes to an abnormal state when any

one of the utility phase voltages is below the setpoint). The setting is entered

based on a phase-to-phase voltage percentage within a range of 70% to 95%

of nominal system voltage. NOTE: The difference between the pickup and

dropout setting is considered the dead band or hysteresis value.

4.6.7.2.Utility Under Voltage Pick Up

Set to the desired utility under voltage setpoint at which the internal voltage

sensor picks up (i.e. the sensor energizes to a normal state when all phases of

the utility phase voltages are above the setpoint). The setting is entered based

on a phase-to-phase voltage percentage within a range of 75% to 100% of

nominal system voltage. NOTE: The difference between the pickup and

dropout setting is considered the dead band or hysteresis value.

PM091 Rev 1 09/02/27 Thomson Technology

TSC 80e TRANSFER SWITCH CONTROLLER

4.6.8. GENERATOR VOLTAGE & FREQUENCY SETPOINTS

The TSC 80e controller provides 3-phase under voltage sensing and under frequency

sensing on the Generator supply. Each sensor is individually programmable for pickup

and dropout voltage setpoints (i.e. adjustable hysteresis). To program the voltage and

frequency sensing features, refer to the following descriptions:

4.6.8.1.Generator Under Voltage Drop Out

Set to the desired generator under voltage setpoint at which the internal voltage

sensor drops out (i.e. the sensor de-energizes to an abnormal state when any

one of the generator phase voltages is below the setpoint). The setting is

entered based on a phase-to-phase voltage percentage within a range of 70%

to 95% of nominal system voltage. NOTE: The difference between the pickup

and dropout setting is considered the dead band or hysteresis value.

4.6.8.2.Generator Under Voltage Pick Up

Set to the desired generator under voltage setpoint at which the internal voltage

sensor picks up (i.e. the sensor energizes to a normal state when all phases of

the generator phase voltages are above the setpoint). The setting is entered

based on a phase-to-phase voltage percentage within a range of 75% to 100%

of nominal system voltage. NOTE: The difference between the pickup and

dropout setting is considered the dead band or hysteresis value.

4.6.8.3.Generator Under Frequency Drop Out

Set to the desired generator under frequency setpoint at which the internal

frequency sensor drops out (i.e. the sensor de-energizes to an abnormal state

when the generator frequency is below the setpoint). The setting is entered in

a percentage value within a range of 70-90%.

4.6.8.4.Generator Under Frequency Pick Up

Set to the desired generator under frequency setpoint at which the internal

frequency sensor drops out (i.e. the sensor de-energizes to an abnormal state

when the generator frequency is below the setpoint). The setting is entered in

a percentage value within a range of 70-90%.

4.6.9. SYSTEM TIMING DELAYS

The TSC 80e provides control and timing delay logic specific to the operation of the utility and generator, these are:

PM091 Rev 1 09/02/27 Thomson Technology

TSC 80e TRANSFER SWITCH CONTROLLER

4.6.9.1.Utility Return Delay

The utility return delay period will be initiated once the utility supply has

returned within limits following a utility power failure condition. Select desired

utility return delay time in minutes. The range of settings is 0.0 to 30.0 minutes.

If no delay is required, set this time delay to zero. NOTE: The utility return

delay will be bypassed should the generator fail during the time delay period.

4.6.9.2.Generator Start Delay

The generator (i.e. engine) start signal will be initiated following expiry of the

start delay timer. Select desired generator start delay time in seconds. The

range of setting is 0 to 60 seconds. If no delay is required, set this time delay

to zero. NOTE: The output relay is normally energized when the utility power

is within limits and de-energizes to start the generator.

4.6.9.3.Generator Speed & Warm Up Delay

A transfer to the generator supply will be initiated when the voltage and speed

(I.e., frequency) are within limits and upon expiry of the warm-up delay timer.

Select desired generator warm-up delay time in seconds. The range of

settings is 0 to 60 seconds. If no delay is required, set this time delay to zero.

4.6.9.4.Generator Cool Down Delay

The generator (i.e. engine) cooldown period will be initiated once the load has

transferred from the generator supply. The engine start signal will be

maintained until expiry of the cooldown delay timer. Select desired generator

cooldown delay time in minutes. The range of settings is 0.0 to 30.0 minutes.

If no delay is required, set this time delay to zero.

4.6.9.5.Neutral Delay

The neutral delay time period will be initiated once both of the supply power-

switching devices are open during a transfer sequence. Select desired neutral

delay time in seconds. The range of settings is 0 to 60 seconds. If no delay is

required, set this time delay to zero. NOTE: The neutral delay may be

bypassed should the operating power fail for longer than the timer setting.

4.6.9.6.Neutral Position Time

The TSC 80e transfer control logic includes an adjustable time delay feature to

compensate for the maximum time that a transfer switch mechanism takes to

operate when load-sensing voltage is used to detect the neutral position. This

PM091 Rev 1 09/02/27 Thomson Technology

TSC 80e TRANSFER SWITCH CONTROLLER

time delay is set to a time value, which is greater than the typical time that the

transfer mechanism typically takes to operate from one supply position to the

neutral position. When the TSC 80e controller is supplied from the factory with

a Thomson Technology transfer mechanism the Neutral Position Delay will be factory set for correct operation.

4.6.9.7.Pre-Transfer Delay

The pre-transfer delay period will be initiated upon an impending transfer in

either direction from a powered-to-powered source. The pre-transfer output

relay will momentarily energize (as per the pre-transfer time setting) prior to a

load transfer and will stay energized until the post-transfer delay time

commences. Select desired pre-delay time in seconds. The range of settings

is 0 to 60 seconds. If no delay is required, set this time delay to zero.

4.6.9.8.Post-Transfer Delay

The post-transfer delay period will be initiated on expiry of the pre-transfer

delay (overlapping) in either direction. The post-transfer output relays will

energize (as per the post-transfer time setting) after the load transfer and will

stay energized until the post-transfer delay time period expires. Select desired

post-delay time in seconds. The range of settings is 0 to 60 seconds. If no

delay is required, set this time delay to zero.

4.6.10.PROGRAMMABLE OUTPUTS

The TSC 80e transfer controller provides programmable output relay functions.

signals. Each output can be assigned one of the following programmable functions.

The output relay energizes when one of the following conditions occurs. NOTE: Only
