The internal switch for the output signal can handle a maximum of +30V
and 100mA. The internal switches pull down the signal level to ground.
Therefore it is very important to mount pull-up resistor(s) and/or a relay(s).
CAUTION: Never connect external voltage directly to the error
and ready output without a pull-up resistor.
Recommended pull-up resistor at +5V: 470 ohm
Recommended pull-up resistor at +24V: 2.2 kilohms
