9 Maintenance, Diagnostics and Troubleshooting

9.1  Maintenance and Service

NOTICE

Updates to Firmware

Contact Danfoss to get a firmware update.

CAUTION

Firmware Modifications

Only Danfoss is authorised to change the firmware. If
other parties make changes to the firmware, the
warranty expires. Furthermore, Danfoss cannot be held
liable for any consequences the changes may have on
the functional safety.

CAUTION

Modifications to the Unit

Only Danfoss is allowed to make hardware modifications
of the safety option. If other parties make changes to
the unit, the warranty expires. Furthermore, Danfoss
cannot be held liable for any consequences the changes
may have on the functional safety.

CAUTION

Servicing

Once a year, check that the safety option functions
properly to ensure the safety of the machine. Perform
the check by testing the safety function and power
cycling the options used in the safety chain.

9.1.1 Yearly Test

According to EN ISO 13849-1, EN IEC 62061 and EN IEC
61508, safety-relevant circuits of the safety option must be
regularly tested to ensure correct functioning. Perform this
test at least once every year. After the power supply has
been connected, the safety option checks its circuits to
switch-off the torque each time the STO function is
selected. The safety option monitors the regular test
interval of its safety-relevant circuits using a time module.

After 1 year in operation, the frequency converter displays
a message that a yearly test must be performed. There are
the following types of a yearly test:

DI1 yearly test: Test only the activation of DI1. No
power cycling required.

DI2 yearly test: Test only the activation of DI2. No
power cycling required.

PUST yearly test: power cycle the frequency
converter, or trigger an external error and press
RESET.

9.2  Repair and Troubleshooting

WARNING

ELECTRICAL SHOCK HAZARD!

Always disconnect mains supply to the frequency
converter before removing the safety option.

Only Danfoss is authorised to repair the safety option. A
defect option must be shipped to Danfoss.

9.2.1 Removing the Safety Option

Before removing the safety option, save all parameters of
the safety option and device settings using one of the
following ways:

Use MCT 10 Set-up Software, see 

MCT 10 Set-up

Software Operating Instructions

.

Execute the LCP Copy operation by selecting 

[1]

All to LCP

 in 

0-50 LCP Copy

. This operation

duplicates the existing parameter settings.

NOTICE

If the safety option is not in the blank initial state when
it is removed, the frequency converter trips with 

Alarm

84

. To prevent this behaviour, set the option to blank

initial state before removing it. This can be done by
resetting the safety option with MCT 10 Set-up Software,
for more information, see 

chapter 6.1.3 Password

Protection

.

NOTICE

If the frequency converter detects a change in the
hardware configuration, the LCP shows 

Alarm 67 Option

Changed

 after a power-up. This situation can occur after

installing or removing an option, or if an option is
defective.

NOTICE

If 

14-89 Option Detection

 is set to 

[0] Protect Option

Config.

, and the frequency converter detects a change in

the configuration, the frequency converter trips with

Alarm 88 Option Detection

 after start-up. This behaviour

prevents any unintended parameter changes. To avoid
alarm 88, set 

14-89 Option Detection

 to 

[1] Enable Option
