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.

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

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 spring loops are slightly compressed. The ratchets will hold the mounting collar and housing in place.

MOUNTING COLLAR (SHOWN IN POSITION) SLIDE COLLAR ONTO THE HOUSING BEFORE WIRING THE REAR TERMINALS

CAUTION: It is not necessary to remove the instrument chassis from the housing for installation. If the instrument 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 instrument.

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.

Label for details

* For 2-wire RTD use terminals 1 & 3, and

place a jumper wire between terminals 3 & 4.

ALARM RESET

An external normally open contact may be wired across terminals 9 & 10 for remote reset. Multiple units can not share common contacts. Terminals 9 & 10 share a common ground with the input.

For relay, NO (Order Code 3) or SSR (Order Code 1) outputs, 15 & 16 and 17 & 18 are Normally Open.

For relay, NC (Order Code 4) outputs, 15 & 16 and 17 & 18 are Normally Closed.

+ -

For Pulsed DC (Order Code 2) and DC SSR (Order Code 8) outputs, 15 & 17 are positive and 16 & 18 are negative.

Wiring for 4 to 20mA Transmitter inputs

Wire power and outputs as shown above. Two-wire transmitters wire as shown below.

For three or four wire transmitters follow the wiring instructions provided with your transmitter.

CAUTION: DO NOT WIRE THE 24 VOLT POWER SUPPLY ACROSS THE INPUT OF THE CONTROL. DAMAGE TO

THE CONTROL INPUT CIRCUITRY WILL RESULT.

Wiring for Optional Inputs and Outputs

Wire power and outputs as shown on page 5 and 6. Wiring for options is shown opposite. All wiring shown below is Class 2. Shielded twisted pair is required for Option 992.

CAUTION: DO NOT RUN SIGNAL WIRING IN THE SAME CONDUIT OR CHASE AS THE POWER WIRING. ERRATIC OPERATION OR DAMAGE TO THE CONTROL CIRCUITRY WILL RESULT.

SWITCH CONTACTS FOR OPTION 948 MUST BE ISOLATED AND CAN NOT SHARE WIRING WITH OTHER CONTROLS.

* Limit Reset key flashes when limit condition is present.

Keys are illuminated when pressed. Key functions are as follows:

INDEX: Pressing the INDEX key advances the display to the next menu item. May also be used in conjunction with other keys as noted below.

UP ARROW: Increments a value, changes a menu item, or selects the item to ON. The maximum value obtainable is 9999 regardless of decimal point placement.

DOWN ARROW: Decrements a value, changes a menu item, or selects the item to OFF. The minimum value obtainable is -1999 regardless of decimal point placement.

ENTER: Pressing ENTER stores the value or the item changed. If not pressed, the previously stored value or item will be retained. The display will flash once when ENTER is pressed.

RST

UP ARROW & ENTER: Pressing these keys simultaneously brings up the secondary menu starting at the SP1d menu item. Pressing these keys for 5 seconds will bring up the secure menu.

INDEX & DOWN ARROW: Pressing these keys simultaneously will allow backing up one menu item, or if at the first menu item they will cause the display to return to the primary menu.

949-1270 Page 8 of 28 December, 1998

LIMIT RESET: This key resets the limit when the limit condition has been removed. Press and hold for three seconds to activate.

INDEX & ENTER: Pressing these keys simultaneously and holding them for 5 seconds allows recovery from the various error messages. The following menu items will be reset:

S1iH: Set Point 1 limit inhibit S2iH: Set Point 2 limit inhibit OPEn InP: Input error message CHEC CAL: Check calibration error

Correct the problems associated with the above conditions before using these reset keys. More than one error could be present. Caution is

advised since several items are reset at one time.

While in the Primary or Secondary Menu, if no key is pressed for a period of 30 seconds, the display will return to the HOME position displaying the temperature value. While in the Secure Menu, if no key is pressed for a period of 60 seconds, the display will return to the HOME position displaying the temperature value. Outputs are disabled (turned off) when the Secure

Menu is active. NOTE: To move to the Primary Menu quickly from any other menu, press

the UP ARROW & ENTER keys followed by pressing the INDEX & DOWN ARROW keys.

SECURITY LEVEL SELECTION

Four levels of security are provided. The display shows the current security level. To change security levels change the password value using the UP & DOWN ARROW keys and pressing the ENTER key. Refer to the password table (following) for the correct value to enter for the security level desired. The SECr menu item security level may be viewed or changed at any time regardless of the present security level.

To set the access level to, for example, 2, at the SECr menu item press the UP ARROW key until the upper display show the password, 1101. Press the ENTER key. The display will blink, and return with the level value, 2, in the upper display.

The password values shown in the table cannot be altered, so retain a copy of these pages for future reference. This is the only reference made to password values in this instruction book.
