Dynalco UM-200 Tachometer / Hourmeter / Monitor - Manual (Page 3)

System Overview
The Dynalco UM-200 is capable of reading up to 2 input channels, calculating differential
value and providing an alarm / shutdown output.
Basic operation:
The UM-200 will be in “stopped” mode until a run indication is sensed. This is selectable as
either a contact closure or magnetic pickup input. Once “running” mode is sensed, the UM-
200 will read both inputs at a rate of 100 msec per channel. If any input crosses either an
over or under threshold, the unit will invoke a flashing red LED on the front panel as well as
an output trip (solid-state relay) that can be used for alarm or shutdown.
Additional Features
• 5 - Digit Hourmeter Function (non-resettable)
• Engine RPM Display
• Fully programmable from front keypad
• Standard SAE case size fits panels with 3-3/8 inch (86 mm) opening

User Interface
The UM-200 is configured via the keypad on the front panel which includes a graphical backlit
LCD display capable of displaying alpha numeric values and custom engineering units of
measure. The keypad implements a menu system, which is navigated using the up, down,
left, right, enter and escape buttons. The backlight will turn off after five minutes of inactivity
and will turn on when any of the keys are pressed.
