GETTING STARTED
1. Install the control as described on page 4.
2. Wire your control following the instructions on page 5. If you are
using a two-wire transmitter as an input, see the drawing and
instructions on page 6. Option wiring instructions are on Page 7.
Option descriptions and specific instructions start on page 16.
3. Most controls do not need many (if any) program changes to work
on your process. For best results when programming changes are
necessary, make all the necessary changes in the Secure Menu
(page 26) before making changes to the Secondary Menu (page 19).
If error messages occur, check the Diagnostic Error Messages on
page 35 for help.
Take the example of a Model 16L2010 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 Unit. 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.

INSTALLATION
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. If more than one
instrument is required, maintain the minimum of spacing requirements as
shown on the drawing below. Closer spacing will structurally weaken the
panel, and invalidate the IP66, UL type 4 rating of the panel.
Prepare the panel by cutting and deburring the required opening.

WIRING
Do not run thermocouple or other class 2 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, auxiliary 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.
Input wiring for thermocouple, current, and RTD; limit reset function; and
output wiring for 15 VDC is rated CLASS 2.
Control wiring is as shown.

NOTATION CONVENTIONS FOR THE MENUS
Because of the number of features available in this control, information is
included that may not apply to your specific control. All usable features are
included in this book, but may not be used in your process. To increase
clarity the following conventions are used:
1. Certain features, Menu Items, and functions shown in this book may or
may not appear on your control, depending on other Menu Item selections.
At various places in the Menus there are notes identifying Menu Items that
"control" or "direct" other menu items. If you are looking for a particular
menu item and can't find it, check the menu item that is its "control" for
proper setting.
2. The "#" symbol is used in two ways. It is used inside a group of
characters to indicate which set point function (SP1 or SP2) is being
affected. It is also used before a group of characters of a menu item to
indicate that there may be more than one selection or value for that menu
item.
3.
Features that apply only to Options will be printed in Italics.
949-1270 Page 10 of 28 December, 1998
THE HOME DISPLAY
The home display is the normal display while the control is operating. The
HOME display may be programmed to operate in one of three different
ways. This is controlled by the diSP menu item in the Secure Menu.
If diSP is set for Pro, the HOME display will show only the Process Variable
(the temperature, pressure, flow, RH, etc., that is being measured) on the
top display with the bottom display blank. If diSP is set for SPt, the home
display will show only the Set Variable (Set Point 1) on the top display with
the bottom display blank. If diSP is set for both, the HOME display will
indicate the Process Variable on the top display and the Set Variable on the
bottom.
If no errors or functions are active, the HOME display as programmed will
be shown.
OPERATION AND PROGRAMMING OF OPTIONS
Option 934, 936, Isolated Analog Retransmission.
The analog retransmission option allows the Process Variable or the
Set Variable to be sent as an analog signal to an external device.
The signal may be either 0 to 10 VDC (Option 936) or 0 (or 4) to 20
mADC (Option 934). The output may be changed in the field from
one to the other by the toggle switch located on the top printed circuit
board.
Wire the output as shown on page 7.
To set up the analog retransmission, first determine the scale range
that the analog signal will represent. The maximum scale is 9999°F,
5530°C, or 9999 counts. In the Secondary Menu set POL for the
scale value that will be represented by the low end of the analog
signal (0 Volts or 0 mA). Set POH for the scale value that will be
represented by the high end of the analog signal (10 Volts or 20 mA).
If you require a suppressed scale or output, you may use the
following equations to determine the proper settings for POL and
POH.
K = (Highest desired scale reading - Lowest desired scale reading) /
(Maximum desired analog signal - Minimum desired analog signal).
POH = ((Maximum possible analog output - Maximum desired analog
signal) * K) + Highest desired analog reading.
December, 1998 Page 11 of 28 949-1270
POL = Lowest desired scale reading - ((Minimum desired analog
output) * K).
Next select whether you want the retransmission signal to follow the
Process Variable or the Set Variable. Usually the Process Variable
is sent to recorders or other data acquisition devices. Usually the
Set Variable is sent to other controls to be used as an analog remote
set point. If you want the analog retransmission signal to follow the
PV, in the Secondary Menu set POSr to InP. If you want the analog
retransmission signal to follow the SV, set POSr to SPt.
Operation is automatic. There are no further programming steps
required.
Option 948, 4-Stage Set Point.
The 4-stage set point option allows four different values to be used
for SP1. The control will switch to a given stage when an external
contact or contacts are made or opened across the appropriate
terminals at the rear of the control (when SPSA, Set Point Switch
Action, is set for remote, rE), or when the stage is selected from the
Secondary Menu, SP (when SPSA is set for Int). When the state of
a contact changes (or the stage number is changed in the Secondary
Menu), the values in use are stored and the previously stored values
for the new stage are used.
Wire the input as shown on page 7.
Usually the control is configured for external switching of the stages.
In this case, the operation is usually automatic, selected by the
external switches driven by the machine logic. If it is necessary to
program the stages in advance, you may select the stage to modify
with the SP menu item. When SP is changed while the SPSA is set
for rE, the selected stage is displayed for modification, but only used
when the appropriate contact is made.
Option 992, 993, Serial Communication.
The serial communications options allow the control to be written to
and read from a remote computer or other similar digital device.
Communication is allowed either through a RS-485 (Option 992)
port, or a RS-232 (Option 993) port.
949-1270 Page 12 of 28 December, 1998
Wire the communication lines as shown on Page 7. Wiring for the
RS-485 is run from control to control in a daisy chain fashion with a
termination resistor (120 ohms) across the transmit and receive
terminals of the last control in the chain.
Select the control address and communication baud rate with the
Addr and bAUd menu items in the Secure Menu. THE BAUD RATE
AND ADDRESS MENU ITEMS WILL TAKE EFFECT ON THE NEXT
POWER UP OF THE CONTROL. BE SURE TO POWER CYCLE
THE CONTROL BEFORE USING THE NEW BAUD RATE AND
ADDRESS.
In operation, you have the option of preventing a write command
from the host computer. To prevent the host from writing to the
control change the LOrE menu item in the Secondary Menu to LOC.
To allow the host to write commands to the control set LOrE to rE.
(The host does have the ability to change the LOrE state, but it is not
automatic.)
If your system depends on constant reading or writing to and from
the host, you may wish to set the No Activity Timer (nAt) to monitor
the addressing of the control. When the LOrE is set to rE and the
nAt is set to any value other than Off, the control will expect to be
addressed on a regular basis. If the control is not addressed in the
time set by the value of nAt, then the control will display the error
message CHEC LOrE. To clear the message set LOrE to LOC.

to zero when the input type is changed, or when decimal position
is changed.
FiLt Digital Filter: Select OFF, 1 to 99. In some cases the time constant
of the sensor, or noise could cause the display to jump enough
to be unreadable. A setting of 2 is usually sufficient to provide
enough filtering for most cases, (2 represents approximately a 1
second time constant). When the 0.1 degree resolution is selected this should be increased to 4. If this value is set too high,
controllability will suffer.
