The power port can deliver a maximum of 84W power (7A max
current). If a connected device draws more than 84W, the port will
automatically shut off to protect the circuitry. After reducing the load,
you can re-enable the port, a process that we'll discuss later.
STATUS LEDS
There are three LEDs on the bridge that indicate the controller's
status:
- The middle LED indicates whether power is flowing to the controller.
- The LED labeled "Over Current" illuminates if the current draw is
greater than the power source can provide. If this happens, either
disconnect or reduce power to one of the devices connected to the
controller or use a power source capable of delivering more current.
You will need to set the max current draw for your power supply for
this LED to work properly (as discussed later in this manual).
If one of the ports has experienced a short circuit from a
l
connected device, the "Over Current" LED will blink, and
the affected port will turn off. You will need to follow the
instructions that appear later in the manual to re-enable the
port and use it again.
- The LED labeled "Under Voltage" will illuminate if the input power
to the controller is less than 11.0V DC. This could happen if your
battery power supply is nearing the end of its charge. In this case,
you would need to use a different power source or recharge the
battery. The under-voltage LED helps protect your battery from
becoming over-drained, which could reduce the battery recharge
lifetime.
If the input voltage of the power source exceeds 13.8V, all
l
output ports will turn off to protect the circuitry, and the
"Under Voltage" LED will blink. In this case, you would need
to replace the power source with one that supplies less than
13.8V and manually re-enable all the output ports according
to the instructions that appear later in this manual.
If you are under dark skies and find the LEDs too bright, you can
adjust their brightness. We'll explain how later in the manual.
ADDITIONAL CIRCUIT PROTECTION
In addition to the status LEDs' warnings, the Smart DewHeater
Controller 2x features other circuit protection measures to keep your
equipment safe.
If the total power draw of the controller exceeds 120W (10A max
current), the controller will automatically shut off. Reduce the load on
the controller and manually re-enable the ports using the instructions
that appear later in this manual.
If you accidentally connect the input power source with the improper
polarity, the controller will not power on to prevent circuit damage.
3. Mounting the Controller to Your Setup
Decide how you want to attach the controller to your telescope setup.
There are a few options:
- Use the integrated dovetail clamp to connect the controller to a
CG-5/Vixen or CGE/Losmandy dovetail bar. If you have a dovetail
bar on your optical tube, this is perhaps the easiest and most
convenient way to connect the controller to your setup. Simply
loosen the controller's clamping knobs, place the controller's
clamps onto the dovetail rail, and then firmly tighten the clamping
knobs (Figure 5).
- Use the included tripod leg strap to attach the controller to one of
your tripod's legs. Insert the strap through the slots in the bottom of
the controller's enclosure, wrap the strap around one of the tripod
legs, tighten the strap with the buckle, and secure the strap end to
itself with the hook-and-loop fasteners on the strap (Figure 6).
- If your tripod's accessory tray is large enough, you can place the
controller on the tray. If you choose this method, keep in mind that
the controller will not be secured in place. Be careful to avoid
forceful cable pulls.
NOTE: DO NOT PLACE THE CONTROLLER ON THE GROUND!
Water and dirt can potentially enter the controller and may cause
electrical problems.

USING THE BRIDGE FOR CABLE MANAGEMENT
The bridge on the enclosure houses the controller's environmental
sensor, isolating it from radiant heat to provide the most accurate
ambient temperature and humidity data. We also designed the bridge
to help with cable management. You can run cables underneath the
