Description
The Series 5000 is designed as a fully programmable digital temperature indicator and miniature datalogger. The displays are 0.56" in-line red LED type. The menu driven display prompts and 14-segment alphanumeric characters make programming simple. Front panel programming is accomplished through three front panel keys. Degrees F or degrees C are indicated by a green, .4" seven segment LED located to the right of the main display. Resolution is selectable either 1° or 0.1°. A single dash (-) displayed at the left of the readout indicates a negative temperature. Positive readings are inferred (no dash displayed). Overload is indicated by an 'OL' on the display. Plus OL (+OL) indicates a positive over range condition or an open thermocouple. Negative (-OL) indicates a negative over range condition. The 5000 is powered by a 100-240Volt, 50-400Hz AC source and uses a switching power supply for maximum input power flexibility.
The unit will accept, depending upon the model, J, K, E, T, R and S thermocouples or 3/4-wire 100 ohm Platinum RTD’s, either .00385 or .00392.
Serial communications is standard RS232. This bi­directional serial port allows the user complete program set­up, programming and operational capability. All controls and features are selectable through the front panel. The front panel lens may be removed to install or remove the program lockout jumper or adjust the analog output if necessary. Power and serial connections to the meter are made to the
1
rear of the instrument via a removable Euro-style terminal block. Sensor connections are made by screw terminals also on the rear of the instrument.
Minimum and Maximum values are always available for viewing. On the Basic model (no options), the information is accessible through the front panel menu system. Configuration settings are stored in on-board memory and are not affected by power loss. The following models are available (see list below).

Installation
Panel Installation
1. Prepare a mounting panel cutout by cutting a rectangular
hole (3.62” +0.02/-0.0” X 1.77” + 0.02/-0.0”) in the desired location (see Figure following page). The maximum panel thickness is 3/8 inches.
2. Remove the mounting bracket from the instrument housing by removing the two screws on the rear of the indicator..
3. Remove the pluggable terminal block located at the rear of the unit and wire the input power and RS232 wires. If an option board is installed in the indicator, remove the connector and make the appropriate connections (refer to diagrams).
WARNING!
Dangerous voltages are exposed at the screw terminals. Always remove power before working in this area for rewiring, disassembly, and all other activities that involve proximity to electrical
3
circuitry. Allow at least 10 minutes prior to working on the unit.

4. Install the indicator in the panel cutout from the front side of the panel. Be sure the instrument is right-side-up. See figure on following page.
5. Reinstall the mounting bracket on the indicator. Tighten the bracket screws to achieve a snug fit against the panel. Avoid distorting or cracking the housing by not over- tightening the bracket screws.

For easy installation, remove the pluggable terminal block located at the rear of the unit. Connect the input power and RS232 wires to the wire entry locations beneath and perpendicular to the plug-in direction according to figure below.
WARNING!
Dangerous voltages are exposed at the screw terminals. Always remove power before working in this area for rewiring, disassembly, and all other activities that involve proximity to electrical circuitry.

Three Wire RTDs
Note: All RTD units are shipped from the factory configured for 4-wire RTDs unless otherwise requested. To enable the unit to measure 3-wire RTDs, remove the electronics assembly from the housing and complete the following steps. If an option card is installed, remove the top and bottom screws and carefully lift the option card from the main board assembly.
Step 1. Remove the jumper located on the topside on the
main board from across pins labeled 4W and install it across the pins labeled 3W.
Step 2. Place the jumper provided across the header labeled
ICOMP. This completes the configuration from 4-wire RTD to 3-wire RTD.

Thermocouple Multiple Input-Wiring
RELAY NC
The Multiple Input Option uses a quick disconnect terminal block to facilitate wire installation and servicing. The terminal block engages the printed circuit board (PCB) fingers of the Multiple Input board which fits through the upper slot located at the rear of the unit. The method of attachment is the same as for a PCB edge connector: push on/ pull off. If desired you can use the two screws that are provided for securing the connector to the instrument case. Note that terminal numbers 13, 14 and 15 are provided for limit relay contact access.
