System
Using the arrows on the keypad, select the “System” icon.
“Display defaults” allows selection of two different screen displays:
“Single Channel” mode displays each individual channel in large format
“Differential” mode displays both input channels plus differential. It also displays
RPM & Hours if the “Run Signal” is configured for “RPM” input.
Note that you are selecting the default layout type. You will be able to change the
layout during normal operation by pressing the left / right arrows.
“Digital output” is used to set the digital output logic as Normally Open or Normally Closed
“Security pin” can be enabled to set up password protection.
Operation
Once programmed, the UM-200 will begin scanning the enabled channel inputs and will
initiate alarms based on over / under threshold values configured for each channel. It is not
necessary to define alarm threshold values for both channels as they may be for monitoring
only.
Alarm / Shutdown Output
The UM-200 will alarm when either channel value or differential value is above or below limits
as specified. Alarms can be configured as either latching or non-latching. If an alarm
condition is met, the red LED on the front panel will blink and the digital output (if enabled)
will trip. Non-latching alarms will reset the alarm if its value returns to normal. Latching alarms
require manual resetting by pressing the “Enter” key on the keypad.
WARNING:
Terminal connection screws to be tightened to 8 inch-pounds torque.
The alarm / shutdown output should be tested monthly for proper operation, especially
if being used for over / under pressure, over / under temperature shutdown or other
critical function.
