ON-SITE REPAIR INSTRUCTIONS
Hardware Integrity Validation
Product Calisto, Calisto 2S/Ns C76 C85 (10620 and up)
NOTICE:The following document contains six sections, 1.0
Electronic Board Verification, 2.0Power Supply Source Validation,
3.0 Power Supply Input Validation, 4.0 Power Switch
Validation, 5.0 Thermal Fuse Validation and 6.0 Power Supply
Validation.
TIME REQUIRED: - 15 minutes
TOOLS NEEDED: - 3/8" flat screwdriver- Multimeter measuring up
to 300VAC and up to 25 VDC
CAUTION
Please follow the procedure carefully to prevent any accidents.
The monitor
must be powered on to determine any malfunction. For this
reason, electricalshocks are highly possible.
Make sure the door is closed when you are not working directly
on themonitor.
Make sure the electrical tools and equipment you use are
properly insulated.
To prevent yourself from being the unintentional path to ground,
make surethe monitor is well grounded.

1.0 ELECTRONIC BOARD VERIFICATION
NOTICE:
At this step a validation that theCalisto is working properly
will be made.
Check the status of the LEDs on the electronic board
assembly.

2.0 POWER SUPPLY SOURCE VALIDATION
NOTICE:
At this step a validation that theCalisto receives enough power
and also that the power supply
is working properly will be made.
Please refer to the figure below for the correct installation of
the power cord. Note that, besidesAC
NEUTRAL andAC LIVE, a third feed line must be provided, the
EARTH line.
Using a multimeter set on voltage measurement, measure the
voltage between pin 1 and pin 2 of the
TB2 connector, see image above. The voltage must be in a range
of 100 V AC and 240 V AC.

3.0 POWER SWITCH VALIDATION
NOTICE:
At this step the integrity of the rocker switch will be
validated.
1. Power onCalisto (if not already done).
2. Be sure that the main fuse is functional, see Section
3.0.
3. Measure the voltage between pin 3 of TB7 connector and pin 1
of TB3 connector then
measure the voltage between pin 4 of TB7 connector and pin 2 of
TB3 connector.
Both voltages must be in a range of 100 V AC and 240 V AC. If
its not the case then please, contact
Morgan Schaffer at [email protected] the code
Rocker switch replacement.

4.0 THERMAL FUSE VALIDATION
NOTICE:
At this step the integrity of the thermal fuse will be
validated.
1. Power onCalisto (if not already done).
2. Check the continuity between pin 1 and pin 2 of the TB7
connector. See figure below:
If there is no continuity then please, contact Morgan Schaffer
at [email protected]
with the code Thermal fuse replacement.

5.0 POWER SUPPLY INPUT VALIDATION
NOTICE:
At this step the integrity of the power supply input will be
validated. The goal is to test the
functionality of the main fuse.
1. Power onCalisto (if not already done).
2. Measure the voltage between pin 1 and pin 2 of the TB8
connector. See figure below:
If there is no voltage then please, contact Morgan Schaffer at
[email protected]
the code main fuse replacement.

6.0 POWER SUPPLY VALIDATION
NOTICE:
At this step the integrity of the internal Power Supply will be
validated.
1. Power onCalisto (if not already done).
2. Using a multimeter set on V DC, measure the voltage between
the two pins of the J11 connector
(see figure below). The voltage should be between 13.1 and 13.25
VDC and steady.
If the voltage is under 12 V, or is not steady, it means that
the power supply is no longer valid
and in this case contact Morgan Schaffer at
[email protected] the code Power
supply replacement.
