13. Channel Bypass
You can use Channel Bypass to take a NotOK or unconnected channel off line. This will
restore the OK Relay to the OK state. The OK Relay will de-energize (go NotOK) if any
channel in the rack is in a NotOK condition.
1. Set BA (Bypass Channel A) or BB (Bypass Channel B) switch to the left (ON) to bypass
channel A or B.
2. The BYPASS LEDs come on, the OK LEDs go off, and the vibration signal is clamped to
zero position (bottom scale).
NOTE
Channel alarms are cleared
when Channel Bypass is
switched on.
Caution
Machine protection provided by this
monitor will be lost while Channel
B
ass is on.
