C. Loop check-out requirements are as follows:
1. Check control signal generation, transmission, reception and response for all control loops
under simulated operating conditions by imposing a signal on the loop at the instrument
connections.
a. Use actual signals where available.
b. Closely observe controllers, indicators, transmitters, HMI displays, recorders, alarm
and trip units, remote setpoints, ratio systems, and other control components.
1) Verify that readings at all loop components are in agreement.
2) Make corrections as required.
(a) Following any corrections, retest the loop as before.
2. Stroke all control valves, cylinders, drives and connecting linkages from the local control
station and from the control room operator interface.
3. Check all interlocks to the maximum extent possible.
4. Utilize a System Integrator provided Loop Check -Out Sheet to document on -site
calibration checks.
5. In addition to any other as -recorded documents, record all setpoint and calibration
changes on all affected Contract Documents and turn over to the Owner.
