LERF Lab 4 is now posted as ODH 2. Please follow the ODH 2 protocol to access the lab.
Currently both ODH sensors in the lab are bypassed. We have tuned both units and will verify their functionality tomorrow. If the readings are within the expected range, we will bring them back online. If not, we will replace at least one sensor; please note that the replaced sensor require 24 hours of stabilization before they can be brought online. Until then, Lab 4 will remain classified as ODH 2.

I think the optimal motor position would have been (-38.4, 4.6)mm rather than (-38.4, 5.0)mm.

Body: The following entry was placed in the Accelerator Bypassed-Interlocks Log (ABIL) Device: OM215 Function: Oxygen Monitor Location: LERF User Lab #4 Purpose: Failing sensor/tx. Exp.

Body: 

OM215, in the LERF, went into alarm. After investigation the head was bypassed. Reason: sensor failures or failing head. Calibration has been performed and the readback is 2.19. The unit will remain bypassed temporarily to monitor readback stability. Overlapping head OM216 is also bypassed, so the area (LAB. 4) is posted as ODH 2.
