512C
The 512C needs two external relays to become directly compatible with the 512 and the 'Run'
terminal must be rewired to provide a high level input to 'Run'. Existing wiring to the 'Health'
and 'Zero Speed' relay contacts must be relocated to the external relays. The Run signal is valid
for Signal Levels from +10 to 24V DC and can be driven from either T14 (+10V) or T19
(Health).
The 'Zero Output' terminal on the 512C must be selected to 'Zero Speed' output by ensuring that
SW4 is 'On'.
