What to do if Chroma 61501 AC Power Distribution shows OVER CURRENT protection (OCP)?
If the Chroma AC Power Distribution unit displays an OVER CURRENT protection (OCP) message, it means the output current exceeds the specified limit or the I LIMIT is exceeded. To resolve this, remove the overload or increase the I LIMIT setting.
What to do if Chroma 61501 AC Power Distribution shows OVER POWER protection (OPP)?
If the Chroma AC Power Distribution unit displays an OVER POWER protection (OPP) message, it indicates that the output power is exceeding the specified limits. To fix this, either reduce the power demand or lower the output voltage.
What to do if Chroma 61501 shows OVER TEMP protection (OTP)?
If the Chroma AC Power Distribution unit is showing an OVER TEMP protection (OTP) message, it means that either the ambient temperature is too high, or the airway is obstructed. To solve this: 1. Ensure the unit is operated within a 0 ~ 40°C environment. 2. Check and clear any obstructions in the airway.
What to do if Chroma 61501 AC Power Distribution shows INPUT FAIL protection (UVP)?
If the Chroma AC Power Distribution unit displays an INPUT FAIL protection (UVP) message, it means that the AC source line input voltage is either too low or too high. You should measure the input voltage and adjust it if it is outside of the specified range.
What to do if Chroma AC Power Distribution shows OUTPUT SHORT protection?
If the Chroma AC Power Distribution unit displays an OUTPUT SHORT protection message, it indicates either the output is shorted or there's an external current reversal. To resolve this: 1. Remove the short circuit. 2. Remove the load.
What to do if Chroma AC Power Distribution shows OUTPUT OVP protection?
If the Chroma AC Power Distribution unit displays an OUTPUT OVP protection message, it indicates that either the remote sense is open, or the output voltage peak is over range. To resolve this: 1. Connect the output to the remote sense terminals. 2. Check the settings of Vac and Vdc on the MAIN PAGE.
Why is the output distorted on my Chroma 61501 AC Power Distribution?
If the Chroma AC Power Distribution unit displays distorted output, it could be due to two reasons: 1. The AC source output voltage is too low; in this case, program a higher output voltage. 2. The rectified load is too large at high frequency; in this case, reduce the load or lower the output frequency.
What to do if Chroma AC Power Distribution shows INT _ AD protection?
If the Chroma AC Power Distribution unit displays an INT _ AD protection message, this could be due to a line input voltage cycle dropout, an instant over current of output, or a damaged AD power stage. To address this: 1. Check the stability of the input voltage. 2. Remove the load. 3. If the protection status cannot be reset, consult the dealer for assistance.
What to do if Chroma 61501 AC Power Distribution shows INT _ DD protection?
If the Chroma AC Power Distribution unit displays an INT _ DD protection message, this could be due to a line input voltage cycle dropout, an instant over current of output, or a damaged DD power stage. To address this: 1. Check the stability of the input voltage. 2. Remove the load. 3. If the protection status cannot be reset, consult the dealer for assistance.
How to fix Chroma AC Power Distribution when it cannot control AC source by GPIB?
If the Chroma AC Power Distribution unit cannot be controlled by GPIB, it may be due to an incorrect unit address or a loose GPIB cable. To solve this: 1. Update the address. 2. Check the connection and tighten the screws.
