    SET POINT INDICATORS - A red LED illuminates to indicate that the set point for the relay, indicated on the overlay, has been exceeded. RS-232 / USB PORT - When used with the Qualitrol software, this port allows for the setup of all of the parameters of the monitor. See the...

  • Page 11: Modules

    LTCs, or fan currents. The input to the module is a clamp on the CT, provided by Qualitrol, which has an input range of 0 - 5 A, 0 - 10 A, or 0 - 20 A, other ranges are available, and an output of 0 - 0.333 VAC, can be used as the input to the CT Input Module.

  • Page 12: Tap Position Input Module (509Itm-300)

    The input to the module is a potentiometer that is typically supplied by Qualitrol. The range of the potentiometer input is up to 15,000 ohm. Typically, the 25° mark on a liquid level dial is set to the center of the potentiometer range, and the high and low readings are simply ratios of the angular deflections from the normal setting.

  • Page 13: Powered Contact Closure Module

    a closed contact signifies a shorted connection across the contacts. This can be used, for example, to monitor pumps or fans. The system internally treats closed and opened contacts as either a 0 or 100 numeric value. Therefore, if the module is used to control a relay, the relay set point should be set at midrange, e.g., 50.

  • Page 14: Installation

    Installation Location and Mounting Installing the Hardware 1. Unpack the 509ITM. 2. Check that all of the materials on the packing slip are included. 3. Make four holes on the transformer panel for installation of the monitor. Important: • Note the mounting differences between the enclosure style and the panel-only style. •...
  • Page 15 Installing power outside of the recommended input range will damage the unit. 10. Energize the 509ITM. The monitor briefly displays “Qualitrol” and the version of the board firmware. Important: The following operation can cause the alarm output state to change.

Warning • Switch off the power supply before performing installation or maintenance. • Hazardous voltage may still be present at the relay area, even if mains power is disconnected.

  • Page 17: Mounting Styles

    Mounting Styles Enclosure (Fiberglass) Style The 509ITM is a 3R fiberglass enclosure, designed to be back-mounted on any smooth surface. Four 0.31 × 0.50 in. oval slots are provided for use with fasteners. The monitor requires an approximate area that is 13 inches in width, 16 inches in height, and 8.5 inches in depth.

  • Page 19: Power Supply

    Power Supply Supply power is applied to Terminal Block TB1 terminals 14 and 15. For DC input, positive voltage is applied to terminal 14, and ground or negative voltage is applied to terminal 15. Chassis ground is applied to terminal 16, as shown in the Power Supply Connection figure. This non-metallic enclosure does not automatically provide a common grounding lug.
  • Page 20 The power supply has an internal removable fuse of GMA 250V/T3.15A (the 5 kV Impulse Unit has no internal fusing) if it becomes necessary to replace this fuse. The fusing must be replaced with the same type and rating that was originally installed. Failure to do so may impact warranty issues.

  • Page 21: Heater Option

    The fuse is the responsibility of the installer. The rating of the heater is 120 VAC and 100 W. A 240 VAC heater uses two of these heaters in a series, for a total of 200 W. Qualitrol recommends installing an external slow-blow fuse rated at 1.25 or 1.5 A, at 600 V. CAUTION: Do not use DC voltage for powering the heater.

  • Page 27: Dry Contact Closure Input Module

    Dry Contact Closure Input Module The Dry Contact (Switch) Closure Input Module is designed to detect the actuation or de- actuation of one dry, non-powered switch contact. The system internally treats closed and open contacts as either a 0 or 100 numeric value. Therefore, if the module is used to control a relay, the relay set point should be set at midrange, e.g., 50.

  • Page 28: Output Contacts

    Output Contacts Nine isolated sets of normally open/normally closed output contacts, for Output Relays 1 - 8 and the System State Output Relay, are provided for controlling cooling equipment, sounding an alarm, or operating remote breaker coils. Each set is capable of switching 115/230 VAC, 30 VDC @ 10 A, and the sets are accessed on Terminal Block TB1, see the Relay Wiring figure for the Enclosure and Panel Mount monitors.

    Consumed Life The 509ITM calculates relative “life consumption” according to IEEE standards. These standards are based on the Arrhenius formulas for deterioration of organic insulation material with time and temperature. Each 6 - 8 degree increase in temperature approximately doubles the rate of life decay. Based on the cumulative exponential affects of temperature over time, the life consumption metering helps to prioritize maintenance activities between transformers.

When the monitor has no power applied, the common and normally closed contacts are shorted together, while the common and normally open contacts are open.
  • Page 176 109.73 ohm 146.06 ohm Because of the small resistance values in an RTD sensor, Qualitrol recommends a maximum of 75 feet of cable length. A typical application to measure the resistance (temperature) changes in an RTD is for a monitor to send an excitation current through the RTD and then measure the voltage across the device.
