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.
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.
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.
OUTPUTS + - For relay, NO (Order Code 3) or SSR (Order Code 1) outputs, 15 & 16 and 17 & 18 are Normally Open. Output A For relay, NC (Order Code 4) outputs, 15 & 16 and 17 & 18 are Normally Closed. Output B + - 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.
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.
FRONT PANEL KEY FUNCTIONS Remote Indicator Limit 1 Lamp Limit 2 Lamp °F Indicator Process Display °C Indicator Set Point Display Limit Reset Key* * 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.
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.
PASSWORD TABLE Menu Security Level Status Displayed Value When Viewed Password Value To Enter Primary Secondary Secure Locked Locked Locked 1 1110 Primary Secondary Secure Unlocked Locked Locked 2 1101 Primary Secondary Secure Unlocked Unlocked Locked 3 1011 Primary Secondary Secure Unlocked Unlocked Unlocked 4 111 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.
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.
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.
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.
