SECTION 1. INTRODUCTION

1.1 UNPACKING

Remove the Packing List and verify that all equipment has been received. If there are any questions about the shipment, use the phone numbers listed on the back cover to contact the Customer Service Department nearest you.

Upon receipt of shipment, inspect the container and equipment for any signs of damage. Take particular note of any evidence of rough handling in transit. Immediately report any damage to the shipping agent.

The carrier will not honor any claims unless all shipping material is saved for their examination. After examining and removing contents, save packing material and carton in the event reshipment is necessary.

Verify that you receive the following items in the shipping box:

QTY DESCRIPTION

1Meter with all applicable connectors attached.

1Owner's Manual

1Set Mounting brackets

1QuickStart Manual

If you ordered any of the available options (except the "BL" Blank Lens option), they will be shipped in a separate container to avoid any damage to your indicator/controller.

SECTION 1.2 SAFETY CONSIDERATIONS

This device is marked with the international caution symbol. It is important to

read this manual before installing or commissioning this device as it contains

important information relating to Safety and EMC (Electromagnetic Compatibility).

This instrument is a panel mount device protected in accordance with

EN 61010-1:2001, electrical safety requirements for electrical equipment for measurement, control and laboratory. Installation of this instrument should be done by qualified personnel. In order to ensure safe operation, the following instructions should be followed.

This instrument has no power-on switch. An external switch or circuit-breaker shall be included in the building installation as a disconnecting device. It shall be marked to indicate this function, and it shall be in close proximity to the equipment within easy reach of the operator. The switch or circuit-breaker shall not interrupt the Protective Conductor (Earth wire), and it shall meet the relevant requirements of IEC 947–1 and IEC 947-3 (International Electrotechnical Commission). The switch shall not be incorporated in the main supply cord.

Furthermore, to provide protection against excessive energy being drawn from the main supply in case of a fault in the equipment, an overcurrent protection device shall be installed.

Do not exceed voltage rating on the label located on the top of the instrument

Note

housing.

Always disconnect power before changing signal and power connections.

Do not use this instrument on a work bench without its case for safety reasons.

Do not operate this instrument in flammable or explosive atmospheres.

Do not expose this instrument to rain or moisture.

Unit mounting should allow for adequate ventilation to ensure instrument does not exceed operating temperature rating.

Use electrical wires with adequate size to handle mechanical strain and power requirements. Install without exposing bare wire outside the connector to minimize electrical shock hazards.

EMC Considerations

Whenever EMC is an issue, always use shielded cables.

Never run signal and power wires in the same conduit.

Use signal wire connections with twisted-pair cables.

Install Ferrite Bead(s) on signal wires close to the instrument if EMC problems persist.

Failure to follow all instructions and warnings may result in injury!

SECTION 2. ABOUT THE METER

2.1 DESCRIPTION

The Differential RTD meter is a value packed indicator/controller. Four full digits accurately display your temperature. Select from DIN (Alpha = .00385) or NIST (Alpha = .00392); 2,3, or 4 wire RTD. Your meter may be a basic indicator or it may include analog output or dual relay output. Analog or dual relay output must be ordered at time of purchase. Analog output is fully scalable and may be configured as a proportional controller, or to follow your display. Dual 5 amp, form C relays control critical processes. Front panel peak detection and memory is also standard. A mechanical lockout has been included to guard against unauthorized changes.

2.2 STANDARD FEATURES

The following is a list of features:

*4-digit, 14 segment LED Display

*NEMA 4/Type 4 Front Bezel

*±0.5° C accuracy

*Automatic Decimal Adjustment

*Non-volatile memory

*115 or 230 V ac 50/60 Hz power supply or 10-32 Vdc or 26-56 Vdc

*T1, T2, T1-T2 display

The following is a list of optional features

*Dual 5 amps, form C relay outputs

*Scalable analog output

*Analog out Proportional control

*Easy setup for proportional control

*Front-panel deviation correction

*Easy RTD error offset calibration

METER BUTTONS

SETPTS Button

In the run mode, press this button to sequentially recall the previous setpoint settings. After using the /T1/T2 and /DEV buttons to alter these settings as desired, press the SETPTS button to store these new values.

Unless you press the SETPTS, /T1/T2 or /DEV button within 20 seconds to store your input, the meter will scroll to setpoint 2 the return to the run mode.

If the dual relay option is not installed or if the “L.3=1” on the “LK.CF” menu, pressing the SETPTS button will display the meter's firmware version.

/T1/T2 Button

In the run mode, pressing the /T1/T2 button will scroll to show T1, T2, and T1-T2.

During the configuration mode or Setpoint modes, use the /T1/T2 button to change the values of the flashing digit shown on the display and/or toggle between menu choices, such as "R.1=F" or "R.1=C". When configuring your setpoint values, press the /T1/T2 button to increment the flashing digit from 0 to 9 by 1's.

/DEV Button

In the run mode press the /DEV button to display the deviation of reading from Setpoint 1.

In the configuration or setpoint modes, press the /DEV button to scroll to the next digit.

2.4 FRONT OF THE METER (Continued)

MENU Button

In the run mode, press the MENU button to terminate the current measuring process and enter you into the configuration mode.

In the configuration mode, press the MENU button to store changes in the non-volatile memory and then advance you to the next menu item.

To lock the MENU button, install S3E jumper. Refer to Table 3-1 for more information about the S3 jumpers.

RESET Button

In the run mode, press the RESET button to:

*reset the latched setpoints. The display will show "SP.RS" (Setpoint Reset).

SECTION 3. GETTING STARTED

Caution: The meter has no power-on switch, so it will be in operation as soon you apply power.

If you power off/on the meter, or perform a hard reset (press the RESET button twice), the meter shows "RST", followed by "D.RTD".

3.1 RATING/PRODUCT LABEL

This label is located on top of the meter housing (Refer to Figure 3-3).

3.2 MAIN BOARD POWER JUMPERS

Important: If you want to change the Factory preset jumpers, do the following steps; otherwise go to section 3.3.

Warning: Disconnect the power from the unit before proceeding. This device must only be reconfigured by a specially trained electrician with corresponding qualifications. Failure to follow all instructions and warnings may result in injury!

To check voltage jumpers, or to change from 115 V to 230 V ac:

1.Remove the main board from the case. Refer to Section 2.7.

2.Locate the solder jumpers W1, W2, and W3 (located near the edge of the main board alongside the transformer - refer to Figure 3-1).

3.If your power requirement is 115 V ac, solder jumpers W1 and W3 should be wired, but jumper W2 should not. If your power requirement is 230 V ac, solder jumper W2 should be wired, but jumpers W1 and W3 should not.

Figure 3-1 shows the location of solder jumpers W1 through W3 on the main board.
