GENERAL DESCRIPTION

Red Lion’s Graphical Panel Meters, PM-50, is a platform of meters designed to increase operator productivity and expose critical plant floor data for use in project scheduling  and process improvements. Local operators can easily relate to the more intuitive graphical display. Additional displays could be added to provide even more data. The meters  feature on-board Wi-Fi, RS-485/Modbus and optional Ethernet or RS-232.
PM-50 features a 4.3″ or 3.5″ Color Graphical Touchscreen.
With an appearance like many smart devices, the display includes a status bar and menu selections for easy operation. Recognizing a swipe gesture allows multiple screens to  be accessed.
Touchscreen push buttons can be displayed on the screen or hidden during operation. The meters mount in standard industrial hole sizes, 1/8 DIN and 1/16 DIN respectively.
On power-up, a Programming Wizard will assist you to get started. You may also select a Programming App, Web Server, or the traditional button/menu style for your  programming needs. For OEM customers a microSD Card allows for quick programming and installation, saving time and money.
The Digital model accepts various pulse sensors. Onboard outputs include two Solid State Outputs that can take up to 30 V source voltage with software configurable source  or sink options. User inputs are also available to provide external interface and control when required.
The PM-50 platform includes modular construction to add additional capabilities. External modules can easily be installed in the field to add a variety of output and  communication options. As safety advances through the Automation Industry, DC is the more common choice for power. However, there are still many requirements for AC  power and they can be accommodated with our AC to DC Power Module.

INSTALLATION ENVIRONMENT

The unit should be installed in a location that does not exceed its own operating temperature and provides good air circulation.
Placing the unit near devices that generate excessive heat should be avoided.
The PM-50 4.3 and 3.5 inch models meet NEMA 4X/IP65 requirements when properly installed. This unit is designed for through-panel mounting. The mounting surface  should have a minimum thickness of 0.04″ (1.02 mm) and maximum thickness of 0.25″ (6.35 mm). Cut the mounting hole per the dimensions shown in the diagram. Care  should be taken to remove any loose material from the mounting cut-out to prevent that material from falling into the unit during installation. Prepare the panel cutout to the dimensions shown.
For hazardous location installation the following shall be taken into consideration:
– The device shall be panel mounted in a tool accessible enclosure with a minimum ingress protection rating of at least IP64 as defined in IEC/EN 60529.
– This device is open-type and must be mounted in a suitable dust-tight end- enclosure in accordance with articles 500 and 502 of the NEC and positioned so only the face of  the display is exposed.
– Must be wired using Division 2 wiring methods as specified in article 501-4(b), 502-4(b), and 503-3(b) of the National Electric Code, NFPA 70 for installation within the  United States, or as specified in section 19-152 of Canadian Electrical Code for installation in Canada.

METER INSTALLATION

Slide the panel gasket over the rear of the unit to the back of the bezel. The unit should be installed fully assembled. Insert the unit into the panel cutout.

While holding the unit in place, place either the top or bottom panel latch on the rear of the unit closest to the panel cutout so that the tabs of the panel latch engage in the slots on the case. Repeat this process with the other half of the panel latch. Secure the latch with the panel mounting screws provided. To achieve a proper seal, tighten the latch screws evenly until the unit is snug in the panel (Torque to approximately 5 in-lbs [56 N-cm]). Do not over- tighten the screws.

EMC INSTALLATION GUIDELINES
Although Red Lion Controls products are designed with a high degree of immunity to Electromagnetic Interference (EMI), proper installation and wiring methods must be  followed to ensure compatibility in each application. The type of the electrical noise, source or coupling method into a unit may be different for various installations. Cable  length, routing, and shield termination are  very important and can mean the difference between a successful or troublesome installation. Listed are some EMI guidelines for  a successful installation in an industrial environment.

1. A unit should be mounted in a metal enclosure, which is properly connected to protective earth.

2. Use shielded cables for all Signal and Control inputs. The shield connection should be made as short as possible. The connection point for the shield depends somewhat upon the application. Listed below are the recommended methods of connecting the shield, in order of their effectiveness.
   a. Connect the shield to earth ground (protective earth) at one end where the unit is mounted.
   b. Connect the shield to earth ground at both ends of the cable, usually when the noise source frequency is over 1 MHz.

3. Never run Signal or Control cables in the same conduit or raceway with AC power lines, conductors, feeding motors, solenoids, SCR controls, and heaters, etc. The cables should be run through metal conduit that is properly grounded. This is especially useful in applications where cable runs are long and portable two-way radios are used in close proximity or if the installation is near a commercial radio transmitter. Also, Signal or Control cables within an enclosure should be routed as far away as possible from contactors, control relays, transformers, and other noisy components.

4. Long cable runs are more susceptible to EMI pickup than short cable runs.

5. In extremely high EMI environments, the use of external EMI suppression devices such as Ferrite Suppression Cores for signal and control cables is effective. The following EMI suppression devices (or equivalent) are recommended: Fair-Rite part number 0443167251 (Red Lion #FCOR0000) Line Filters for input power cables: Schaffner # FN2010-1/07 (Red Lion #LFIL0000)

6. To protect relay contacts that control inductive loads and to minimize radiated and conducted noise (EMI), some type of contact protection network is normally installed across the load, the contacts or both. The most effective location is across the load. a. Using a snubber, which is a resistor-capacitor (RC) network or metal oxide varistor (MOV) across an AC inductive load is very effective at reducing EMI and increasing relay contact life. b. If a DC inductive load (such as a DC relay coil) is controlled by a transistor switch, care must be taken not to exceed the breakdown voltage of the transistor when the load is switched. One of the most effective ways is to place a diode across the inductive load. Most Red Lion products with solid state outputs have internal zener diode protection. However external diode protection at the load is always a good design practice to limit EMI. Although the use of a snubber or varistor could be used. Red Lion part numbers: Snubber: SNUB0000 Varistor: ILS11500 or ILS23000

7. Care should be taken when connecting input and output devices to the instrument. When a separate input and output common is provided, they should not be mixed. Therefore a sensor common should NOT be connected to an output common. This would cause EMI on the sensitive input common, which could affect the instrument’s operation.

WIRING

WIRING All power, input and output (I/O) wiring must be in accordance with Class I, Division 2 wiring methods and in accordance with the authority having jurisdiction. Electrical connections are made via pluggable spring-clamp terminal blocks. It is recommended that the power supplied to the meter be protected by a fuse or circuit breaker.
When wiring the meter, refer to the label on the unit for pin-out numbering against those shown in the wiring drawings for proper wire position. Strip and connect the wire according to the terminal block specifications on Page 3. Use a small screwdriver to press down on tab next to the terminal position to open the spring clamp. Insert the wire into the terminal position and then remove the screwdriver to engage the spring-clamp.

POWER WIRING
Must use a Class 2 circuit according to National Electrical Code (NEC), NFPA-70 or Canadian Electrical Code (CEC), Part I, C22.1 or a Limited Power Supply (LPS)  according to IEC/ EN 60950-1 or Limited-energy circuit according to IEC/EN 61010-1.

Ensure software configuration is set to correspond with your required application wiring.

Shaded areas not recommended for counting applications.

USER INPUT WIRING

User Input terminal does not need to be wired in order to remain in the inactive state.

Sinking Logic
When the parameter is programmed to Low, check with device GUI option. The user inputs of the controller are internally pulled up to +3.3 V with 20 KΩ resistance. The  input is active when it is pulled low (<0.9 V).

Sourcing Logic
When the parameter is programmed to High, check with device GUI option. The user inputs of the controller are internally pulled down to 0 V with 20 KΩ resistance. The  input is active when a voltage greater than 2.4 VDC is applied.

ON-BOARD DUAL SSR WIRING

The SSR outputs require meter configuration to address their functionality.
The drawings below illustrate the wiring for each option.
