Honeywell HC900 Control Station Model Number 900CS10-00 PDF Installation

These instructions explain how to install your Control Station. Once installed, the unit must be configured. Configuration is a detailed process described in other documents. The overall steps for getting your Control Station up and running are as follows. Install the unit per this instruction sheet. Refer to other documentation for details on the following steps. After completing installation, configure the HC900 controller for your application using Hybrid Control Designer software and save the .cde file. Using Station Designer software, create data tags from your .cde file, create your operator interface configuration and save the .sds file. Download the .sds file to the 900 Control Station and verify operation.
Note: Configuration of the 900 Control Station may be performed prior to mounting if found to be more convenient when using the USB port since once loaded the configuration is maintained in non-volatile memory, but doing so requires the station to be connected to a 24Vdc power supply.
Supplied separately
• Adapter Plate Kit (optional, use if replacing Honeywell 1042 Operator Interface.)
• Flash Memory Module (optional) Note: The Flash Memory Module must be a UL approved component to maintain UL station approval when installed. With the 900 Control Station positioned face down on a clean, flat surface, and with connectors facing you, locate the Flash Memory Module receptacle through the access hole on the right side of the case. Insert the Flash Memory Module into the connector, face-side up, being sure the card is fully engaged in its receptacle. The Flash Memory Module should not be installed or removed while the Control Station has power
applied.

ATTENTION: If you are replacing a 559 or 1042 Operator Interface, skip this step and go to page 11 instead. Using the drawing below, cut panel hole. You can use the cardboard template as a rough guide but be sure to measure against the drawing below before cutting. Drill holes using a 3/16 inch (4.76mm) size drill bit. Remove any loose material from the mounting cut-out to prevent that material from falling into the Control Station during installation. Mount the gasket by placing its 14 holes over the Control Station’s 14 mounting bolts. Push gasket all the way on to the mounting bolts. Insert Control Station into panel cutout. Install the 14 kep nuts provided with the Control Station. Tighten evenly for uniform gasket compression. Do not tighten the kep nuts beyond a maximum of 17 inch-pounds (1.92 N-m) or you may cause damage to the Control Station’s front panel.

General wiring considerations
• Use Division 2 wiring methods as specified in Article 501-4 (b), 502-4 (b), and 503-3 (b) of the National Electrical Code, NFPA 70 for installation within the United States, or as specified in section 19-152 of Canadian Electrical Code for installation in Canada.
• The Control Station cables contain low voltages. Keep cables away from high voltage wires that can cause interference.
• CE testing was performed with shielded, twisted pair cables. For noise reduction tips, see Honeywell document 51-52-05-01, How to Apply Digital Instrumentation in Severe Electrical Noise Environments.

Connect to earth ground
The back of the unit has a chassis ground terminal identified with the symbol earth ground (protective earth). The chassis ground is not connected to signal common of the unit electronics. Maintaining isolation between earth ground and signal common is not required to operate the unit, but when connecting the HC900 controller to the unit using the recommended shielded CAT5 Ethernet cable, a path to earth ground is created via the Ethernet shield of the controller. Other equipment connected to the unit may require isolation between signal common and earth ground. To maintain isolation, care must be taken when connections are made to the unit. For example, a power supply with isolation between its signal common and earth ground must be used. Connecting a device via a USB cable may also connect signal common and earth ground. The shield of the USB’s connector at the host may be connected to earth ground. A USB’s shield may also be connected to signal common.
4. Mount and connect power supply The Control Station requires a 24 VDC power supply rated at 29 W or more. Your unit may draw considerably less than rated power depending upon the options being used. As additional features are used your unit will draw increasing amounts of power. Items that could cause increases in current are additional communications, Flash Memory Module, and other features programmed using Station Designer software. It is important that the power supply is mounted and wired correctly if the unit is to operate reliably. Please take care to observe the following points.
• The power supply should be mounted close to the unit. Recommended not more than 6 feet (1.8 m) of cable between the supply and the Control Station. Ideally, the shortest length possible should be used.
• A power supply with isolation between its signal common and earth ground must be used.
• The wire used to connect the power supply to the Control Station should be at least 22-gage wire. If a longer cable run is used, a heavier gage wire should be used.
• The routing of the cable should be kept away from large contactors, inverters, and other devices which may generate significant electrical noise.
• A power supply with a Class 2 or SELV rating should be used. A Class 2 or SELV power supply provides isolation to accessible circuits from hazardous voltage levels generated by a mains power supply due to single faults. SELV is an acronym for “safety extra-low voltage.” Safety extra-low voltage circuits shall exhibit voltages safe to touch both under normal operating conditions and after a single fault, such as a breakdown of a layer of basic insulation or after the failure of a single component has occurred.
• If the power supply will be mounted in a hazardous location, it must be rated for Class I, Div. 2 by an OSHA recognized NRTL, such as UL or FM.
• Using the terminal block provided, connect the power supply’s +24Vdc lead to terminal 2 and the Common lead to terminal 1. See figure below. Plug the terminal block into the connector located on the bottom of the interface.
