The “Jog” section of the setup screen is where you set the amount that the JG+/JG- will change
the value. For example, if the “Jog” is set to 5KW, then pressing JG+ on the number entry screen
will increase the entry value by 5. This feature allows for quick value changes. Touching this area
will load an entry screen.
2
The Cooldown selection is the amount of time the system will keep the fans running after the
“Fan” switch turns to “Off” in order to allow the elements to cool after use. Touching this area
will load an entry screen.
3
When “KW Regulate” is enabled, the load bank will regularly sample voltage, recalculate the rat -
ed load step KW values, then add or remove load steps to maintain the desired KW. When “KW
Regulate” is disabled, the load bank will only sample voltage when load is applied or changed.
4
The KWHR setting serves a running total of service hours.
5
Selecting “MAN” will load the manual selection screen. This menu allows for selection of indi -
vidual steps for testing purposes.

6.6.2 Error Reporting Menu
The Error menu (as seen in Figure 10) will show what’s wrong with the load
bank. If there is a loss of amperage from the cooling fans, then the Cooling Fan
Failure indicator will illuminate. If the Exhaust Temperature is greater than 235°
F (~112° C), the “High Exhaust Temp” indicator will illuminate. If the metering
communication is disrupted, then “Metering System Fault” will be indicated for
your attention. The “Load OK” option will be displayed if the load is within a set
range. If it is over or under that desired range, an “Over KW Fault” or “Under KW
Warning” will be displayed. To remove the respective indicator, you must address
the problem. To remove the respective indicator, please see “Table 5 Trouble
Shooting Table” on page 26 for some resolutions

6.6.3 Auto Jog Settings
The load bank includes an Auto Jog feature to cycle through various load steps for
a set period of time. The way Auto Jog works is by starting at the Minimum KW
for a set interval. When that interval lapses, the KW is increased to the next step
repeating this process until the Maximum KW is reached. After KW is decreased,
the process repeats until stopped (Figure 13).
