The model 1604 monitor is designed to provide simultaneous, continuous surveillance of RTD's to monitor motor or other equipment's temperature for overheating. The RTD temperature is compared to the pre-selected trip points set by the customer, and when the temperature equals or exceeds the preselected value, a dedicated RTD alarm relay will trip. The alarm detail can be viewed to identify the alarm location and details. Two temperature set-points are available.
Each channel has a dedicated alarm relay for the higher temperature, and there is a common relay for the pre-alarm set-point. Each channel allows a memo to be inserted in a field that can be displayed in the event of an alarm. Incoming alarms can be viewed in detail at the display, while the event results are saved in a history text file. The 1604 monitor accepts industrial standard RTD inputs for Nickel, Platinum and Copper characteristics. There is no calibration required for the monitor.
Programming is implemented by utilizing a standard USB PC keyboard, temporarily connected to the front bezel. Preset temperature values can be programmed into the monitor as well as RTD - specific messages. At completion of programming, a configuration report can be printed out for review. History reports are available and can be viewed on the monitor or printed via a USB memory stick.
Open or shorted RTD's will initiate a fault menu to identify exactly where the problem exists. When the monitor is entered program mode, a fault will be issued. A dedicated fault relay will change state upon a fault or when the monitor is in program mode.
