5.1 Exchange of consumables
5.1.1 Exchange of the power module
The HYDRA COMPACT can be connected to independent power nets. If one of the three power modules or a power
net is failing you can hear a buzzer alarm that can be reset by pushing the red buzzer reset button [4] at the
front of H
YDRA COMPACT. The failing power module can be replaced with a spare module without power down the
H
YDRA COMPACT. Besides the alarm buzzer there is a visual indication of a power failure via the green LED [7] at
the front. This LED is blinking in case of a power error. Then the defective power module can be located by exam-
ining the individual LED’s [37] of the power modules at the back of H
YDRA COMPACT. If the green LED on a power
module is off, the module is defective and must be replaced.
Only authorized personnel should carry out this maintenace work!
• Locate the defective power module by examining the green LED’s [37] on the individual power modules. If
an LED is not lightened the respective power module is defective.
• Unplug the power cord from the mains connection [32, 33 or 34] of the defective power module!
• Loosen the securing screw [31] at the lower side of the bracket [30] that fixes the power modules with a
size 2 Phillips screwdriver and remove the bracket. Keep the bracket and the screw.
Use gloves to remove the power module. The cover of the power module is been used as
heat sink for cooling, usually the temperature is around 50 – 60° Celsius under full
condition!
• Press the metallic handle bar [38] towards the rubber handle bar [36] unless the power module is no
longer locked in the housing and pull it outwards.
Put the power module aside for cooling down. Keep it away from other people unless it has
cooled down!
• Take a good power module. Insert the power module into the system! Push it inside the housing unless the
metallic handle bar [38] snaps in.
• Reattach the bracket [30] and fix the securing screw [31].
• Re-plug the power cord to its mains connection [32, 33 or 34]!
• Check if the green LED [37] turns on!
• Check the green LED power failure [7], which indicates the total power system status. The LED may not
blink!
