Yaskawa Z1000U HVAC Matrix Bypass - Manual (Page 309)

u Parameters Listed in Dark Gray Rows
Parameters and multi-function selections in the following tables that appear in dark gray rows are only available
by directly connecting an HOA keypad to the drive inside of the bypass enclosure.
Refer to the Z1000U Programming Manual (SIEP C7106160 10) for details on these parameters and selections.
WARNING! Electrical Shock Hazard. Before opening the bypass enclosure, disconnect all power to the equipment. To prevent electric
shock, wait at least 60 seconds before opening the cabinet. After opening the cabinet, verify that the charge indicator on the drive is OFF.
Measure for unsafe voltages to confirm the drive is safe prior to servicing. Failure to comply may result in death or serious injury.
NOTICE: Parameters listed in dark gray rows in the tables below do not normally require modification. Incorrectly setting these drive
parameters may adversely affect bypass performance. Use caution when changing drive parameters to avoid erroneous settings.
Use the following procedure to view and change parameters listed in dark gray rows:
1.
Remove all Run commands from the bypass package or set parameter Z1-06 = 0 to force the package to be in “OFF”
state upon power-up.
2.
Power down unit, wait for 60 seconds, then open the cabinet and verify that the charge indicator LED is extinguished.
Measure for unsafe voltages prior to proceeding to Step 3.
3.
After the bypass enclosure is open, disconnect the RJ-45 cable from the back of HOA keypad mounted to the enclosure
door.

Close and latch cabinet door then apply power.
6.
View/modify parameters or settings as needed.
7.
Power down unit, wait for 60 seconds, then open the cabinet and verify that the charge indicator LED is extinguished.
Measure for unsafe voltages prior to proceeding to Step 8.
8.
Open bypass enclosure and disconnect the customer-supplied RJ-45 cable connecting the HOA keypad and Z1000U
drive.
9.
Reconnect the RJ-45 cable from Step 3 to the back of the HOA keypad mounted to the enclosure door.
