Error Messages

"Manual" exposure mode could not be set
Promote Control could not set the camera to "Manual" exposure mode as required by the current operation. The camera is likely incompatible with the exposure mode automation used by Promote Control, but it may still be used with a minor manual intervention. Use the camera controls to set the camera to "Manual" exposure, then disable the Automatic Exposure Mode control setting in the Setup Menu section.

A "Bulb" exposure is required. Please allow and connect an optional shutter cable
The current operation requires the optional shutter cable to be connected. See Connections section on how to connect a shutter cable.

Exposure time could not be set. Enable "Auto Exposure Mode" or set camera to "Manual" exposure
Promote Control could not set the shutter speed required by the current operation. This may happen due to a number of reasons.

First, check if you set Enable camera settings check/sync Setup setting to "No", and set it back to "Yes". This helps diagnosing most of the problems.

If the problem persists, there are a few possible reasons:

Problem: Promote Control tried setting an exposure time before camera was ready.
Solution: If you are using a shutter cable, use Shutter cable release frame delay Setup setting to add more delay before shots. If you are NOT using a shutter cable and only use USB connection, use USB cable release frame delay Setup setting to add more delay betwen shots.

Problem: Camera has not been set to "Manual" exposure mode.
Solution: Set the camera to "Manual" exposure mode using the camera controls.

Exposure time could not be set
Make sure your camera is set to "Single" drive mode, as opposed to "Continuous". Quiet or Silent mode is also acceptable, if available on your camera.
Make sure your camera is set to "Manual Focus" mode.
Make sure your camera is set to "Manual Exposure" mode.
If you enabled "Long Exposure Noise Reduction" setting on your camera, make sure Promote Control has its LeNR setting set to "On". Promote Control will try to match those settings for you, but if this attempt fails, an error may be shown.
Make sure that the "Mirror Lock-Up" (MLU) settings on your camera and Promote Control are matched - both need to be either "On" or "Off". Promote Control will try to match those settings for you, but if this attempt fails, an error may be shown.

Camera cannot be recognized
The device connected to the Promote Control USB port is using an unknown, non-camera protocol or is not a camera. Verify you have a compatible camera connected and it is appropriately configured as described in Camera Setup section.
An up-to-date list of compatible cameras can be obtained from our website at http://www.promotesystems.com/.

Please set camera USB connection mode to "PTP" and reconnect the camera
The camera connected needs to be reconfigured to use the PTP protocol for USB communications. See Camera Setup section for more details.

Programmed sequence falls out of exposure range
One or more scheduled exposures of the current operation are outside the range available with your camera and Promote Control. This error message may be seen when using High Dynamic Range mode and one or more required exposures is faster than 1/4000 and the Setup setting named Enable exposures below 1/4000 is not enabled (subject to camera support). See High Dynamic Range Mode section for more information about how to continue

Exposure out of range
Previous topic Next topic Print this topic
One or more shutter speed in a High Dynamic Range sequence cannot be set. Choose another value for the "Mid Exposure" setting to continue.

Device battery may go low during exposure sequence
This message is shown when Promote Control senses the battery charge is low and may become fully depleted before the current operation completes. You may proceed if the current operation is an unusually short one. However, you should replace the batteries as soon as possible when this message appears.

LOW BATTERY
Promote Control determined the battery charge is too low for normal operation and will automatically power off to prevent being damaged from excess battery discharge. Replace the batteries with a fresh set before continuing.
