Input Logic

The controller inputs are capable of accepting either NPN or PNP

outputs. The default setting is configured as a sinking input to

connect to a PNP sourcing output. In order to connect the input

to an NPN output the jumpers In1 and In2, on the main PCB, must

be adjusted as described in Table 3 and Figure 2.

Table 3: Input Logic as Described by Jumper Settings

Figure 2: Input Logic Sinking/Sourcing Is Defined by the Jumper Setting

Output Logic

The 45MLA controller uses push-pull outputs that can be

connected to either sinking or sourcing input cards. Additionally,

the output logic can be inverted using DIP switch S1:5. The

procedure to do this is detailed in the sections describing each

controller.

Jumper Connect to PNP Output (Default) Connect to NPN Output

In1 Input IN1 active 'high' (+24V) Input IN1 active 'low' (0V)

In2 Input IN2 active 'high' (+24V) Input IN2 active 'low' (0V)

LED Indicators

The following table indicates the status and description for each

LED on the controller’s main PCB.

DIP Switches

DIP switch settings and descriptions are detailed in model-

specific sections in this document. Change DIP switch settings

only when the controller power is off.

Potentiometer Settings

The time settings of outputs Out1 and Out2, overhang duration

(t_ot) and minimum output duration (t_out), can be adjusted

using the corresponding potentiometers, as described by the

following table.

via DIP switch 4).

 Potentiometer 1 is not used on the analog controller model.
