I simply write the test cases that will be ok I think

1 Atm connected to electricity it should be in ON state 
with proper message
2 Atm not connected not electricity it should be in OFF 
state 
3.ATM should ask for password before going to profile of 
customer
4.ATM should check for money limits set for day/ month 
based on user 
 and so on   it goes sdepends on ur thinking

I guess there could be test conditions as

1) Atm in working condition. ATM doesnt need electricity. 
2) Does it ask for a password when you insert the card.
3) Max amount withdrawn should be set.
4) Try withdrawing money with an odd no to see if it 
responds
 The list is endless

No this is not exact answer please give perfect answer, that
both answers might be wrong.
