The OPEN function will operate the motor in the open

direction as set by the OPEN mode, while the CLOSE

function operates the motor in the closed direction as set

by the CLOSE mode. The LATCH function will maintain

the previously selected function; this allows momentary

switches to be used for the OPEN and CLOSE functions.

The OFF and STOP functions turn the motor off, which

also unlatches the OPEN or CLOSE functions.

Note that the OPEN and CLOSE functions may work in

reverse until the open and closed positions are set by the

OPEN and CLOSE modes.

automatically turn the motor off when the open or closed

positions are reached.

occurs (see FAULT INDICATOR), the motor will be turned

on for a period of 15 minutes in the selected direction. For

this reason, limit switches should be used when using the

OVERRIDE mode, and should be set to a position

acceptable for the application. The 15 minute period can

also be terminated using the OFF or STOP function.

The motor is also automatically turned off if the TDC-100

detects a stall (see STALL DETECTION). An OPEN or

CLOSE operation can be attempted again after switching

to the OFF, LATCH, or STOP functions first.

AUTO

The AUTO function is the normal mode of operation for

the TDC-100; all the other functions are used to set up

the unit. While in AUTO, the unit can be controlled by

various external signals, some of which can be selected

by the COMMAND INPUT function. When the unit is not

in the AUTO mode, all external controls described below

will be disabled.

Once the open and closed positions have been set, the

AUTO mode will control the position of the actuator

according to the command input signal. For an input

signal of 0V (for 0-5V or 0-10V input), 1V (for 1-5V input),

2V (for 2-10V input), 4.0 mA (for 4-20mA input), or 0% (for

a digital input), the TDC-100 will position the actuator to

the closed position as set by the user. Conversely, an

input of 10V, 5V, 20mA, or 100% will position the actuator

to the defined open position.

When the TDC-100 is configured to use a 0-5V, 0-10V, 1-

5V, or 4-20mA command, the command signal should be

connected to the appropriate pin on J2 - note that the

unused input pin must be left unconnected. When the

TDC-100 is configured for a Digital command type, an

appropriate communications option module must be

installed. A communications module may be installed

when using one of the analog command types and can be

used to override the analog command. The AUTO

indicator will flash whenever the unit is being controlled

by the communications module.

MANUAL/FB POT CAL

The MANUAL/FB POT CAL function allows

manual operation of the actuator by using the adjust

buttons (▲ and ▼) without affecting any other settings

within the TDC-100. When the ▲ button is pressed, the

motor winding connected to J1-1 is turned on while the ▼

button turns on the J1-3 winding. Whether the actuator

moves toward the open or closed position depends on

which motor winding is connected to J1-1 and J1-3.

The POT CAL feature provides an indication of the

feedback potentiometer's setting.

AL/POT CAL function is selected, the Manual/Pot Cal

indicator will turn on - it may flash or be on steady,

depending on the actuator position. The indicator will be

on steady whenever the TDC-100 detects that the

feedback potentiometer is at midrange of its rotation. As

the actuator moves, causing the feedback potentiometer

to move away from midrange, the indicator will begin to

flash, and the indicator will flash at a decreasingly slower

rate as the actuator moves further away from midrange.

By using the adjust buttons to position the actuator to

midstroke (half way point between the desired open and

closed positions), the feedback potentiometer can then be

adjusted until a steady light occurs. This insures that the

feedback potentiometer has maximum range to reach the

open and closed positions.

The CLOSE function is used to set the desired closed

position; however, prior to doing this, the feedback

potentiometer should be checked for optimum position

(see MANUAL/POT CAL), and the limit switches should

be set outside of the operating range (see STALL

DETECTION FEATURE). In the CLOSE function, the

adjust buttons are used to set the actuator to any desired

position, and upon pressing the MODE button (to select

the next function, OPEN), the TDC-100 will retain the

setting as the defined closed position.
