WARNING

If a network problem occurs, an unexpected dangerous voltage may occur that may
cause electric shock, fire, physical damage to the DUT, and so on. If you are going toremotely control the PLZ-5WH2 from a distance, install a Web camera or take othermeasures to monitor the status.

Connection
Use a LAN cable (category 5 or better, straight) to connect the PLZ-5WH2 using method (a) or (b).
(a) Connect the PLZ-5WH2 to a corporate LAN or router.
(b) Connect the PLZ-5WH2 directly to the PC or through a switching hub.

 Configuring the PLZ-5WH2
When the PLZ-5WH2 shipped from the factory, the IP address assignment method is set to automatic.
Unless there is a special reason otherwise, you can simply use these settings for methods (a) and (b).
If you want to use a fixed IP address, on the PLZ-5WH2’s front panel, press SYSTEM > Interface > Modify> Edit. Set Method to Static, and set IP Address, Subnet Mask, and Default Gateway as you like. For
details, see “System Configuration” the user’s manual.

 Checking the PLZ-5WH2’s IP address
To control the PLZ-5WH2 from Wavy through LAN, you need to know the PLZ-5WH2’s IP address.
If you are going to use the PLZ-5WH2 with the factory default settings, the PLZ-5WH2’s IP address will be
automatically assigned. To check the IP address, follow the procedure below.

1 On the PLZ-5WH2’s front panel, press SYSTEM > Information.
2 Turn the rotary knob to display IP Address.

Sequence Overview
Sequence is a function that executes a sequence of operations set in advance.

Programs and steps
A sequence consists of programs and steps. A program is a collection of steps. Steps are executed inorder one at a time, starting from step 1. The completion of the last step signifies that the program has
been executed once. The same program can be executed for a specified number of times, or different
programs can be executed consecutively (only when in the same operation mode, using the chain
function). When all programs have been executed, the sequence stops.

Sequence
Set a program for each operation mode. Up to 30 programs can be set.
Up to 10000 steps total can be used in all programs.
If transition method of step 1 is set to Ramp, the start current of step 1 will always be 0 A.

• Do not create more than 10000 steps. If the total number of steps exceeds 10000,
unexpected behavior may result.
• Wavy does not check the validity of the settings for the PLZ-5WH2. Do not set a step to avalue outside the PLZ-5WH2 range specifications. If you transfer a program containing
invalid values to the PLZ-5WH2, you will not be able to run it.

 Load value transition method
The available load value transition methods are step and ramp. With step, the load value transitions stepwise from the value of the previous step. With ramp, the load value transitions in a ramp from the value ofthe previous step.

You can use the protection functions available on the PLZ-5WH2 (hardware settings) and those available
on Wavy (software settings).

Hardware settings are protection (alarm) functions available on the PLZ-5WH2. You can set overcurrent
protection (OCP), overpower protection (OPP), undervoltage protection (UVP), and watchdog protection.

Roll mode

The X-axis and Y-axis are scrolled at the same time according to the elapsed timeand load values. The display range is defined by subtracting the minimum timevalue from the maximum time value.

Normal mode

The minimum time is fixed. The maximum time is updated to the appropriate value.
If you want to scroll only when the monitored value exceeds the maximum X-axis
value, select the “Scrolling within the specified range” check box.
The amount of time that the graph will be scrolled by is determined by subtracting
the minimum time value and the set scroll time from the maximum time value.
For example, if the minimum time is set to 0 seconds, the maximum time to 23
seconds, and the scroll time to 10 seconds, the time range that will be scrolled is 13
