INTRODUCTION
Welcome to the Norman family of interchangeable high-quality flash equipment and thank
you for purchasing a Norman Monolight system. The utilization of larger high-duty-cycle
flash capacitors and related components enables this system to be utilized for demanding
commercial and portrait silver halide and digital applications that are not normally associated
with monolights.
FEATURES
o
o
600 watt-second capacity. The ML600 is an honest 600 watt-seconds (1500 w-s by
today’s advertising)
1/20-stop repeatability at full power. Holds this tolerance with line voltages from 105
to 125 volts.
o
o
o
250 watt quartz modeling lamp with fan cooling.
Digital controls with LED display. Adjustable in 1/10-stop increments.
Error condition diagnostic readouts via internal software, as displayed in the LED
arrays (page 7).
o
o
Automatic thermal protection (page 7).
Interchangeable with over 100 Norman accessories and light modifiers with adapter
ring (part no. R9113).
o
Full two year limited warranty, including parts and labor.

5. SYNC Outlet
CONTROL PANEL / OUTLETS / BASIC OPERATION
The camera connects to this outlet via the R4155 Sync Extension Cord (included). The socket
(female) end of the Sync Extension Cord connects to the camera sync cord (not included).
Most 35mm and 120mm cameras utilize a standard “PC” sync cord which is available through
your photo supply store.
Proper polarity is important with cameras that utilize grounded shutter switch circuits
(cameras that utilize PC cords). If the unit does not flash on initial set-up the polarity may be
reversed. To achieve the correct polarity – Reverse the camera sync cord at the point where it
joins the Sync Extension Cord. This establishes a common ground between the camera body
and the flash unit. If the polarity is incorrect the unit could self-flash or flash intermittently.
6. Photo Eye (Slave)
Permits remote triggering from other flash units. The Photo Eye is automatically disabled
when a ¼” sync plug is inserted in the SYNC outlet.
7. RESET 10 Amp Circuit Breaker
Automatically protects the flash circuit against excessive overloads. When activated, it will
pop out about ¼” and the unit will become inoperative. To reset, wait at least 30 seconds and
depress the RESET button. If the circuit breaker continues to activate, consult the factory or
your authorized Norman service center.
8. Flash Power +/- Pushbutton Switches and LED Display
Controls the unit output in 1/10-stop increments over a 5-stop range plus “full” (6-stops total).
Tap the + or – pushbutton switch for each 1/10-stop change. Hold the pushbutton switch
down and the change accelerates for convenience. Once the approximate power level is
obtained, tap the pushbutton switches until the desired setting is obtained.
The LED can display the output in two modes: f-stop reduction or watt-seconds power level.
Press both the + and – pushbuttons at the same time for at least 2 seconds to change display
modes.
1. AC Power Inlet
Error conditions are displayed on the LED, as outlined on page 7.
Connects to the AC power cable. The AC input is 115 volts, 60 Hz. The unit is voltage
stabilized to provide 1/20-stop full power repeatability with AC line voltage fluctuations of 20
volts (105-125 volts).
9. Ready Light
The unit is fully charged when the Ready Light is on. At minimum power (18.75 w-s) the
recharge time is approx. 0.5 seconds, and at maximum power (600 w-s) the recharge time is
approx. 2 seconds. The unit may be flashed before it reaches full charge.
2. Power Switch
Switches the AC power on/off. A memory circuit retains the output settings when the unit is
switched back on or when the AC power is interrupted.
10. Flash Verification
Flash verification will visually indicate when the unit has flashed. The modeling lamp will
cycle on and off, then return to its previous state.
3. Modeling Lamp
Depress the pushbutton switch to toggle between the three modeling lamp modes:
FULL - The modeling lamp is at full brightness regardless of the flash power setting.
RATIO - The modeling lamp will automatically ratio (track) with the flash power
setting.
This function can be enabled / disabled by toggling the Flash Verification pushbutton switch.
11. Computer Control Modular Jack
OFF - The modeling lamp is off (indicated by both the Full and Ratio LED’s off).
4. TEST Button
The unit can be flashed by depressing the TEST button. When changing power levels, power
can be discharged through the flashtube instantly with this button instead of waiting for the
power to be bled through the discharge resistor of the internal circuitry.

ADVANCED OPERATION
GENERAL TROUBLESHOOTING
Unit will not flash:
Alarm System
In the event of a misfire the LED display will blink bFL (see page 7). The alarm system is
reset automatically by flashing the unit or by pressing any button on the control panel.
•
•
Flashtube is not installed properly. (see page 4)
Sync cord polarity not correct (see ‘SYNC Outlet’ page 6)
Unit does not turn on:
Thermal Protection
•
•
Check power cord
Check circuit breaker
The ML600 is protected with an internal overtemp cutout. In the event of an overtemp, the
modeling light will be disabled.
Photo Eye does not flash unit:
•
•
Sync cord is plugged in (see page ‘Photo Eye’ page 6)
Trigger flash is out of range
SERVICE
Modeling light will not turn on.
•
•
•
Modeling lamp is not installed properly (see page 4)
Modeling lamp is broken
Modeling lamp is turned off. Check the control panel switches (see page 5)
Should not be attempted by user. Consult an authorized Norman Service Center.
Modeling lamp or flashtube replacement. Always unplug unit and discharge stored energy
by pressing the Test button. Wait 10 minutes for any residual charge on the main capacitors to
bleed off and let the flashtube and modeling lamp cool before handling. Always handle
modeling lamp with clean gloves or cloth to avoid transfer of body oils to lamp dome.
Carefully remove old flashtube and/or modeling lamp and replace with new.
Note: If you are still experiencing trouble after checking the above general troubleshooting
guideline contact Photo Control Customer Service.
Never place metal object or fingers into modeling lamp or flashtube sockets.
