Product Introduction
Inputs Signal Specifications:
A single transducer signal from a proximity probe transducer or magnetic pickup is
accepted by each Overspeed Detection module. The input signal has a voltage range
of +10.0 V to -24.0 V. Signals that exceed this range are internally limited by the module.
133396-01 Front Panel LEDs
OK LED: Indicates that the 3500/53 Module is in good working order.
When the 3500/53 Module is talking with other modules in the 3500 rack, the TX/XR
LED illuminates.
If the 3500/53 Module is in Bypass Mode, the Bypass LED illuminates.
When the 3500/53 is in Test Mode, the Test Mode LED illuminates.
Alarm LEDs: Indicates that an alarm condition has occurred with the associated relay.
Transducer Conditioning
Auto Threshold: Use for any input over 0.0167 Hz (1 rotation per event). The minimum
triggering signal amplitude is 1 volt peak-to-peak.
Manual Threshold: Selectable by the user from +9.9 Vdc to -23.9 Vdc. The minimum
triggering signal amplitude is 500 millivolts peak-to-peak.
Hysteresis: 0.2 to 2.5 volts, user-configurable.
Alarm Setpoints:
Speed may be changed to Under and Over Alert levels (setpoints). A Danger (Overspeed) setpoint can also be set for speed. All alarm setpoints are configured using software. Alarms are customizable and may typically be adjusted from 0 to 100% of the full-scale range of speed.
Frequency Response Speed Input:
With a maximum full-scale range of 99,999 rpm and a maximum input frequency
of 20 kHz, the 3500 Overspeed Protection Module will support from 1 to 255 events
per revolution. The minimum input frequency for proximity transducers is 0.0167 Hz
1 rpm for 1 event/revolution), whereas the minimum input frequency for passive magnetic pickups is 3.3 Hz.
