Dan and I  disconnected TM1 in ITW.

Disconnected EXIT1 in ITW. All cables , wires and air lines are label marked.

TM4 has been disconnected in ITE. Vacuum pumps and gauge are not disconnected yet.

TM2 has been disconnected in ITW. All water lines are nitrogen purged. Filled 60 psi argon to all Tm2 water lines for module storage in winter shut down.

ITW entrance module has been disconnected.  All connections are labelled before or during disconnection. The 24VDC electrical plug on ITW TP1S is broken . It will be replaced with a new plug. The lift yoke is installed onto module without difficulty.   

 David and I disconnected entrance module in ITE by following the procedure # 190510. And, the yoke was installed and left on for remote handling later. 

Dan and I replaced flow wheel on ITE HVC2 water flow sensor. The old wheel did rotate smoothly inside its SST case. The new wheel works fine.

I DISCONNECTED TM4 IN ITE. ALL WATER LINES HAD BEEN PURGED OUT WITH PRESSURE AIR.

[edit 2023-01-03] The crane was powered back on this morning - there do not appear to be any faults and it seems that the crane was unaffected by the power outage.

The ISAC target hall overhead crane was powered off for the holidays. Note that this may result in the commonly observed PLC battery failure issue when the crane is powered back on in the new year.

The target hall crane has been powered down by Don today in preparation for the power shutdown over the Holidays.

The crane pendant for the main hoist was upgraded to a FLEX EX2 style pendant by Canco Cranes. The installation work was performed by Matt at Canco, supervised by Tom Kauss, David Wang, and Adam Newsome. Installation work was performed in two phases since the initial installation did not provide adequate range and an antenna issue needed to be resolved (I2021-01-14-1, and I2021-02-16-1).

Items installed include:

• New pendant
• New antennae
• New receiver box, mounted on main crane control panel in the crane control room

The old receiver control box will be kept for some time in case there is a need to revert to the previous system for some reason.

The new system was tested by David Wang - including using the pendant at the far end of the target hall where range was previously an issue. Everything is reported to be in working condition. Remote mode is functioning as expected.

 When lifting up TM2 (20000lbs) this afternoon, TH crane has a strange noise on main hoist. The module was lift up less than 1 feet.when strange sound was noticed.  The module move was stopped right away,and module  was lowed back to SHC. The strange noise was confirmed later with SEG block six inches lifting up. Gordon crane technician will be here to tomorrow morning to investigate the problem.

In the AM today David and I used the crane to raise the ground plate sheet metal into place. This afternoon when I attempted to return the crane to its usual place I discovered that the crane no longer worked. Upon further inspection it appears that the PLC has lost power. I will follow up on this Monday morning. The crane is not supporting any load at this point.

 Turns out I am just not very observant. David had turned the main break to the crane off as a result when he turned it back on this morning the crane magically started working again.

Today, I checked TH crane main hoist  when shielding plug is installed into ITE pit. I did  some jogging actions on main hoist during the operation. Everything looks fine. No burning smell, no strange noise. An outside crane expert suggest that jogging is the worst working situation for crane. We have to use jogging actions during our crane operation. But, we could try to use less jogging when operate the crane.

The Target Hall Crane has been shut down in preparation for the power outage tomorrow (Dec 22). Power will be restored on Dec 23.

Dec 23 update: power has been restored. The crane appears to be in working condition as there is no fault indicator on the PLC.

 The power to the crane and controls were turned off using the power switch in the Crane Control room.  The main disconnect switch in the target hall was not touched.

All site power will be off for a period of time during the Christmas break and this removes the crane from any issues when power is restored.

An issue was observed in which the target hall crane was not functioning: the N-E-S-W and up/down motions did not work, however the rotation motion did work. These symptoms were similar to what was observed in the past under https://elog.triumf.ca/TIS/RH-ISAC/2039 and https://elog.triumf.ca/TIS/RH-ISAC/1845

The crane control console was not powered (i.e. pressing the ON/OFF buttons when the selector switch was set to remote mode, even when safety conditions were met, did not enable/disable remote functionality). The power supplies were checked and everything appeared to be powered as would be expected, except for items which depended on the main contactor (O-K1) being energized. This contactor needs the PLC to be in an operational state, fault-free. The PLC was checked and the red fault light was flashing. The battery light was not on (i.e. battery was OK).

The program was re-downloaded to the PLC. During an attempt to go online with the PLC, error code 0004h appeared (see attached image for description). This is an unfamiliar error code - typically the aforementioned symptoms arise due to a battery failure and the program being lost. In this case it is uncertain at this time what the cause of this fault is. It will be monitored in the future to determine if it occurs again, and further investigation will be performed.

After re-downloading the program and placing the PLC in RUN mode, the crane was fully restored to its operating state - the main contactor was able to be energized once again. The crane was put into remote mode and a brief functionality test on the motion axes was performed: OK.
