Description of Signals:
Earth : Supply voltage output
+5V : Supply voltage output
24V : Supply voltage output (for external voltage supply or extraction
M24 : Supply voltage output by adjustment to internal voltage supply))
CYa/BWa : Carry or borrow output of counter 1, 2 or 3
active: high - max. 24V, 50mA
inactive: high-impedance
UAxa : Counter input 1 or 2 for counter 1, 2 or 3
active: high
24V - level
UA0a : Reset counter 1, 2 or 3
active: high
24V - level
If UA01(pin 10), UA02 (pin 6) and UA03 (pin 2) are not used, they can be
left open.
