DXXXXXXXX 12 Volt Power Supply MCS-SI-BASE Expansion Board SHIELDWIRE-GROUNDING multi-terminal connectors Five (5) port Ethernet Switch UL 508A Certified Industrial Control Panel Benefits of selecting an Industrial Control Panel that carries the UL 508A certification include: · UL 508A certification provides the inspection authority and your customer evidence that the control panel complies with nationally recognized safety standards. These standards ensure public safety and provide assurances that the Industrial Control Panel is compliant with national and local electrical codes. · For a control panel to carry the UL 508A Listing Mark, the panel must contain only UL recognized and listed components. The UL Mark on a component means that UL has evaluated and tested samples of this component and has concluded that they meet the UL requirements. This protects the quality and integrity of the enclosure and provides guarantee of safe performance. RTHA/RTHB Industrial Control Panel MCS-MAGNUM-N-12 The MCS-MAGNUM-N-12 is a durable microprocessor based controller designed for the hostile environments in the HVAC/R industry. It is designed to be the primary manager of the package it is controlling. The Magnum provides flexibility with set points and control options that can be selected prior to commissioning a system or when the unit is live and functioning. The TouchScreen and MCS-CONNECT provide a clear and simple language that informs the user as to the status of the controller. Touchscreen The MCS-TOUCH-15.4 capacitive touchscreen interface designed to simplify user access with the MCS-Magnum and MicroMag utilizing MCS-Connect to provide both graphics and service mode access to technicians. Input method: Finger, glove, stylus. Highly accurate and does not require calibration - easy to clean glass surface. Works outdoors, bright screen, water resistant, Exceptional Optics - 1280x800 resolution, sharp and vibrant images. MCS-TOUCH-15.4 comes preloaded with the MCS-CONNECT program that allows you to view the `unit's status', `extended history', `alerts', `alarms', setpoints, and more, all in a user-friendly graphic format. SYSTEM OVERVIEW COMPRESSOR OVERVIEW SCREEN EVAPORATOR CONDENSER OVERVIEW SCREEN OPTIONAL `GRAPHS OVERVIEW SCREEN IN REAL TIME' RTHA/RTHB Industrial Control Panel MCS-SI-BASE The MCS-SI-BASE provides a flexible and cost effective way to allow sensor input and analog output expansion for the MCS MAGNUM. Each MCS-SI-BASE has a standalone microprocessor which communicates with the MCS MAGNUM over the MCS-I/O port at 38,400 baud. All data is check summed with auto error correction. Because communication is over a RS-485 long distance two-wire differential network transmission system, the MCS-SI-BASE may be located up to 5,000 feet away. Each MCS-SI-BASE board can be powered by a 12VDC regulated power supply and has a automatic power fail reset system. MCS-VOLTAGE-3PH The MCS-VOLTAGE-3PH measures AC voltage between 200-600 AC. It is designed to monitor the voltage of each phase of the main input power to the unit. The MCS-VOLTAGE-3PH sensor provides three separate DC voltage outputs that correspond to the AC voltage it's measuring. MCS-PHASE The MCS-PHASE is a programmable 3-phase line voltage monitor with 25-fault memory, high temperature LCD display, easy setup and clear diagnostic readout of system faults. The MCS-PHASE was specifically designed to protect motors and other 3-phase loads from premature failure and damage due to common voltage faults such as unbalance, over/under voltage, phase loss, reversal, incorrect sequencing and rapid short cycling. MCS-PRESSURE TRANSDUCERS The MCS Pressure Transducers are one of the most economical and durable options on the market for dealing with high-pressure industrial applications. In addition to being CE and UL approved, MCS transducers are capable of surviving high vibration. They include a cavity built out of solid 17-4 PH stainless steel ¼" SAE Female Flare fitting & Schrader valve; 7/16-20 UNF pipe thread which creates a leak-proof, all metal sealed system that makes the transducers ideal for use with rugged HVAC environments. RTHA/RTHB Industrial Control Panel MCS T100 Temp Sensor An extremely fast acting temperature sensor built for demanding environments. It is ideal for high moisture locations with continuous freeze and thaw cycles. The sensor is potted with a thermally conductive RTV Cure Silicon Adhesive to guarantee durability and response. Its high accuracy allows for interchangeability in the field. The large resistance range allows the use of over 1000' of cable with no noticeable effect. The MCS-T100 sensor has the ability to move from 32ºF to 212ºF in approximately 10 to 15 seconds. MCS-Wells/Tubes The MCS-WELL was designed to be used with the MCS-T100 temperature sensor, although it has other applications. It is used in the RTHA series chillers in the chilled water and condenser water lines. It comes pre-filled with heat conductive compound to aid in temperature to the sensor. 1/2 - 3" 1/4- 2.5" The MCS-TUBE can be epoxied to a discharge or suction line on the RTHA series chillers in order to obtain temperature readings without the use of a well. It was designed to be used with the MCS-T100 temperature sensor and comes pre-filled with heat conductive compound to aid in transferring temperature to the sensor. MCS-USB-RS485 The MCS-USB-RS485 is a USB to RS485 cable that provides a fast simple way to connect a MCS-MAGNUM to a Laptop or PC. The MCS-USB-RS485 cable contains a small internal electronic circuit board, which converts USB to RS485 with LED indicators for transmit (TX=Red) and receive (RX=Green). MCS-EPOXY · Pre-measured resins and hardeners in one tube · Easy to use - bonds, seals, plugs, molds and rebuilds · No special tools needed · Can even harden under water · Pressure tested to ................ 1300 psi · Temperatures up to .............. 500 degree F · Color..................................... Gray · Density ................................. 15.9 lb/gal (1.9 g/cc) · Hardness (Shore D) ............. 85 · Tensile Strength ................... 6000 psi · Compressive Strength ......... 18.000 psi · Modulus of Elasticity ............ 6 x 105 psi · Shear Strength ..................... 700 psi RTHA/RTHB Industrial Control Panel MCS-CT500 MCS-CT500 current sensor monitors current flowing to electrical equipment. The magnitude of the current is converted to a linear output voltage between 0.06 to 4.52vdc which can be read as a standard analog input signal. The signal is used by MCS micro controllers for the following: 1. For slide valve control on screw machines 2. For high amp motor overload protection 3. For verification of device on / off RTHA/RTHB Typical Options BMS GATEWAY The MCS-BMS-GATEWAY is a microprocessor based communication device that provides translation from Bacnet IP, Bacnet MSTP, Modbus IP, Lontalk, or Johnson N2 communication interface. Information that can be transmitted includes the status of control points, alarm information, digital inputs, analog inputs or setpoints. The MCS-BMS-GATEWAY protocol is field selectable by setting jumper on the device. Using MCS-CONFIG and the CONFIG files for the MCS-MAGNUM, you can automatically create the CSV files that is required by the MCS-BMS-GATEWAY. MCS-EXV-DRIVER MCS-SEHI The MCS-EXV-DRIVER is used for the positioning and control of Sporlan, Alco, Carel, and Danfoss bipolar expansion valves using an analog input of 0-10 VDC (0 VDC = 0% valve opening, 10 VDC = 100% valve opening). The MCS-EXV-DRIVER also supports overdriving on full opened and full closed voltage signals. The display decimal notifies when overdriving by blinking. The MCS-SEHI are Electronically Operated Step motor flow control valves, intended for the precise control of liquid refrigerant flow. Synchronized signals to the motor provide discrete angular movement, which translates into precise linear positioning of the valve piston. Valve pistons and ports are uniquely characterized, providing improved flow resolution and performance. The MCS-SEHI valves are easily interfaced with MCS microprocessor based controllers.
