Danfoss VLT Programming Guide

NB!
The setting in par. 14-20
Reset Mode is disregarded in case of Fire Mode being active (see par. 24-0*, Fire Mode).
14-21 Automatic Restart Time
Range: Function:
10 s* [0 - 600 s] Enter the time interval from trip to start of the automatic reset function. This parameter is active
when par. 14-20
Reset Mode is set to Automatic reset [1] - [13].
14-22 Operation Mode
Option: Function:
Use this parameter to specify normal operation, to perform tests or to initialise all parameters except
par. 15-03
Power Up's , par. 15-04 Over Temp's and par. 15-05 Over Volt's . This function is active
only when the power is cycled (power off-power on) to the frequency converter.
[0] * Normal operation Select
Normal operation [0] for normal operation of the frequency converter with the motor in the
selected application.
[1] Control card test Select
Control card test [1] to test the analog and digital inputs and outputs and the +10 V control
voltage. The test requires a test connector with internal connections.
Use the following procedure for the control card test:
1. Select
Control card test [1].
2. Disconnect the mains supply and wait for the light in the display to go out.
3. Set switches S201 (A53) and S202 (A54) = ‘ON’ / I.
4. Insert the test plug (see below).
5. Connect to mains supply.
6. Carry out various tests.
7. The results are displayed on the LCP and the frequency converter moves into an infinite
loop.
8. Par. 14-22
Operation Mode is automatically set to Normal operation. Carry out a power
cycle to start up in Normal operation after a control card test.
If the test is OK:
LCP read-out: Control Card OK.
Disconnect the mains supply and remove the test plug. The green LED on the control card will light
up.
If the test fails:
LCP read-out: Control Card I/O failure.
Replace the frequency converter or control card. The red LED on the control card is turned on. To
test the plugs, connect/group the following terminals as shown below: (18 - 27 - 32), (19 - 29 - 33)
and (42 - 53 - 54).
