GETTING STARTED

1. Install the control as described on page 4.

2. Wire your control following the instructions on page 4 and drawing on
page 5.

3. Most controls do not need many (if any) program changes to work on
your process. For best results if programming changes are necessary,
make all the necessary changes in the Secure Menu (page 10) before
making changes to the Secondary Menu (page 8). If error messages
occur, check the Diagnostic Error Messages on page 15 for help.

Take the example of a Model 25011 that comes from the factory pro­grammed for type J thermocouples. Suppose for this example you wish to
change the input to type K and limit the set point range between 0° and
1000° C.

First, enter the Secure menu as instructed on page 5. Press the INDEX key
until the display shows Inp and press the DOWN ARROW until the display
shows CA. Don't forget to press the ENTER key to retain your setting.

Next, press the INDEX key to display F-C. Press the DOWN ARROW until
the display shows C. Press ENTER.

Next, press the INDEX key until SPL is displayed (pass the dPt and InPt
selections). Press the UP ARROW until the display shows 0. Press
ENTER.

Finally, press INDEX key to display SPH. Press the DOWN ARROW until
the display shows 1000. Press ENTER.

The necessary program changes are now complete. After 30 seconds the
display will switch back to the temperature reading. If you want to return
faster, press the UP ARROW and ENTER keys (at the same time) and then
press the DOWN ARROW and INDEX keys ( again at the same time). This
will 'back out' of the menu and immediately display the temperature reading.

MODEL IDENTIFICATION

Model 2 5

Output

Alarm

0 = No
1 = Yes

Mount the instrument in a location that will not be subject to excessive
temperature, shock, or vibration. All models are designed for mounting in
an enclosed panel.

Select the position desired for the
instrument on the panel.
Prepare the panel by cutting and
deburring the required opening.

From the front of the panel, slide
the housing through the cut out.
The housing gasket should be
against the housing flange before
installing.

Input

1 = Thermocouple, J,K,T,E,N,L
2 = RTD, DIN, NIST, Ni 120

INSTALLATION

1 = SSR
2 = 5 VDC
3 = Relay
5 = Current

From the rear of the panel slide the
mounting collar over the housing.
Hold the housing with one hand
and using the other hand, push the
collar evenly against the panel until the springs are compressed. The
ratchets will hold the mounting collar and housing in place.

It is not necessary to remove the control chassis from
the housing for installation. If the control chassis is
removed from the housing, you must follow industry
standard practice for control and protection against
Electro-Static Discharge (ESD). Failure to exercise
good ESD practices may cause damage to the control.

WIRING

Do not run thermocouple or other input wiring in the same conduit as
power leads. Use only the type of thermocouple or RTD probe for which
the control has been programmed. Maintain separation between wiring
of sensor, auxilliary in or out, and other wiring. See the "Secure Menu"
for input selection.

For thermocouple input always use extension leads of the same type
designated for your thermocouple.

For supply connections use No. 16 AWG or larger wires rated for at least
75°C. Use copper conductors only. All line voltage output circuits must
have a common disconnect and be connected to the same pole of the
disconnect.

Wiring to housing terminals while chassis is re­moved may cause distortion of the internal connec­tor and possible damage to the connector when the
chasis is re-installed. It is strongly recomended that
the control housing be wired with the chassis in­stalled.

Control wiring is shown below.
