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: a regular output contact OUT107 (JMP23 in
position 2–3) or an extra Alarm output contact (JMP23 in position 1–2). See Table 2.3 and Table 2.4 for more information
on jumper JMP23.
