|
ITE:ANODE supply reading strange currents - 17mA with the power supply on and no voltage. Checked anode circuit from electrical room:
Anode wire in electrical room shows 0L at 250V
Circuit with 50kOhm resistor mostly looks good (49-52kOhms) but a couple times read 28kOhms, no idea why. Tried jiggling all cables, unplugging |

Monday, January 27, 2020, 10:40, David Wang, Cooling, Maintenance, , , ITE/ITW supply water presuure on dump circuits.
|
With both stations in operation,ITE dump supply gauge reading is 27 psi. ITW is 20 Psi. I adjusted ITW dump pressure to 25 psi by changing the
return line side pressure relieve valve.
ITE full operation+ ITW no TM: ITE dump pressure 27psi, ITW dump pressure 27psi. |
