Inputs, Outputs, Timers, and Other Control Logic
Output Contacts
q PULSE command is also available via the front panel ({CNTRL} pushbutton, output contact testing option).
Execution of the PULSE command results in a logical 1 input into the above logic (one-second default pulse width).
w Output contacts OUT101–ALARM are configurable as a- or b-type output contacts. See Table 2 .2 for more information on
selecting output contact type.
e Main board jumper JMP23 allows output contact OUT107 to operate as: regular output contact OUT107 (JMP23 in
position 2-3), an extra Alarm output contact (JMP23 in position 1-2). See Table 2 .3 and Tab le 2 .4 for more information on
jumper JMP23.
