Operation
Alarm/Warning Conditions
The owner/operator is alerted to Alarm and/or Warning
conditions via the control panel LCD. All Alarm conditions
cause the generator to shut down.
The Warning messages alert the operator to conditions
that do not disable the unit or require immediate
correction.
The possible Alarm/Warning messages are listed below.
Alarm Messages
• High Engine
Temperature
• Low Oil Pressure
• Overcrank
• Overspeed
• RPM Sense Loss
• Underspeed
• Controller Fault
• Ignition Fault Code
• Auxiliary Shutdown
• WIRING ERROR
• Over Voltage
• Under Voltage
• Overload
• Missing Cam Pulse
• Missing Crank Pulse
• Low Fuel Pressure
• E-Stop
NOTE: Unless correctly trained to correct and clear
Alarm/Warning conditions, contact an IASD or trained
service technician.
Changing Date/Time
To change date/time after activation, see Navigation
Menu in Figure 4-2. If power is lost (battery is discon-
nected/reconnected, control panel fuse is removed/in-
stalled, etc.), display automatically prompts user for Date/
Time. All other information is retained in memory.
Programmable Timers
For operation instructions of the Power Zone 410, see the
technical manual.
Dealer Programmable
Exercise Time
A programmable exercise time is provided. In AUTO, en-
gine starts and runs once each week at time and day
specified. During exercise cycle, unit runs approximately
24

12 minutes and then shuts down. Transfer of loads to
generator does not occur unless utility power fails.
NOTE: A dealer password is required to change duration
of exercise cycle.
User Programmable
Startup Delay Timer
A programmable line interrupt delay (or startup delay)
timer is provided. When utility voltage fails (falls below
60% of nominal), the startup delay timer is started. If volt-
age rises above utility volts low threshold, timer is reset. If
utility voltage remains below utility volts low threshold
during the duration of the timer, unit cranks and starts.
NOTE: Factory default setting is five seconds, but is ad-
justable from 2 to 1,500 seconds.
Warm-Up Delay Timer
A programmable warm-up delay timer is provided. As
soon as generator starts, the warm-up timer starts. When
the warm-up timer expires, controller transfers load to
generator (through transfer switch) if utility voltage is less
than 80% of nominal. If utility voltage is greater than
threshold at expiration of warm-up timer, load is not
transferred to generator and a cool-down period begins.
At the end of the cool-down period, generator stops.
NOTE: Factory default setting is five seconds, but is ad-
justable from 5 to 1,500 seconds.
USB Port for Firmware Updates
A USB port is located beneath the rubber flap on the con-
trol panel, and is provided for firmware updates. Firmware
updates must be performed by an IASD.
IMPORTANT NOTE: USB port is intended for use with
a USB thumb drive only. USB port is not intended for
charging devices such as phones or laptops. Do not
connect any consumer electronics to USB port. Con-
tact an IASD for any firmware updates.
Battery Charger
NOTE: Battery charger is integrated into control panel
module.
The battery charger verifies:
• Output is continually optimized to promote maxi-
mum battery life.
• Charging levels are safe.
NOTE: A warning message is displayed on the LCD
when the battery requires service.
