4.5. Protected
Mode
When the SLSLLG2 operates in Protected Mode, the device will shut down if run
for too long over 10 Hz. This is in order to protect the device from overheating. The
unit does not monitor the temperature directly, but the time limit is based on
calculations assuming no heat control at room temperature. If the user utilizes
some kind of heat mitigation system, they may set the unit to Unprotected Mode
where the time limit alarm is ignored and the device will operate continuously. Note
that operating the shutter in Unprotected Mode may damage the unit.
The following table outlines the length of time the device can be operated safely
above 10 Hz.

4.6. Unprotected
Mode
The SLSLLG2 normally operate in Protected Mode. In this mode, the unit will
disable the blades, turn the Status LED red, and trip the interlock when the unit is
run over 10 Hz and the time limit is reached (see Specifications on page 15 for
more information). In Unprotected Mode, the unit will not disable under those
conditions.
To enter Unprotected Mode, hold both the POWER and ENABLE buttons until the
Status LED flashes amber four times. While in Unprotected Mode, the Status LED
will remain amber, so any condition that normally would be green will now be
amber. To exit Unprotected Mode, depress both buttons until the Status LED
flashes green four times. This will put the device back into External Modulation
Mode. Depressing the ENABLE button while in Unprotected mode, will exit
Unprotected Mode and enter Manual Mode. The LED will turn green.
