Installation
• Only qualified personnel is allowed to install and perform the connection of PCA-10 into
customer's system
• PCA-10 is intended only for capacitor charging applications. The module should only be
used inside the medical equipment, which has means to isolate its circuits electrically
from the supply mains on all poles simultaneously
• Use four M4 mounting holes on the bottom side of PCA-10 for fixation of the module in
your system. Refer to the Dimensional drawing section for their location. Note: max.
tightening depth of mounting screws should not exceed 4mm
• Connect the module to your system protective ground using provided M4 grounding
thread. Note: max. screw depth should not exceed 6mm
• Connect INPUT, HV OUTPUT and INTERFACE cables according to their functions
• Since module is air cooled, at least 50mm of free space should be provided both at the
suction and pressure sides of PCA-10
Operations
1. Disable the high voltage output using INHIBIT signal (PIN7 of INTERFACE)
2. Set the desired output voltage in working range (0V-V
to the Voltage Program (PIN3 of INTERFACE)
3. Apply power to the module, wait 2-5s until module starts
4. Enable the high voltage output (PIN7 of INTERFACE)
5. After operations disable the high voltage output,
then disconnect module from the mains
Faults
Fault
Overvoltage (Pin 19, pin 14)
Short-circuit (Pin 19)
Open-circuit (Pin 19)
Overtemp (Pin 13)
Cause of the fault
Voltage on the load exceeds
110% of V
level
MAX
HV OUTPUT is enabled, but
voltage doesn't increase in
predefined time (1.5-2.0s)
There is no capacitive load
connected to HV OUTPUT
Temperature of internal elements
exceeds the preset limit (approx.
85°C)
) by applying a DC voltage
MAX
Troubleshooting
The fault signal will disappear after
elimination of its cause and resetting
INHIBIT signal (inhibit and enable the
signal referring to the INTERFACE
description)
The fault signal will disappear after
elimination of its cause and resetting
INHIBIT signal (inhibit and enable the
signal referring to the INTERFACE
description)
The fault signal will disappear after
elimination of its cause and resetting
(turning off and on) mains supply of the
charger
The fault signal will disappear automatically
after the temperature decreases below the
limit (approx. 75°C)
