1. If after pressing 1 active run button and then not pressing all
active run buttons within 5 seconds. After an additional 5
seconds the message will occur.
2. During single stroke mode and at the end of a normal stroke,
the PM is looking for all active run buttons to be released within
1 second of deĆenergizing clutch valve outputs.
3. After the arm continuous button is released, if all
active station run buttons are not released within 0.1 second.
IN GENERAL, THESE MESSAGES OCCUR TO PREVENT THE
FOLLOWING:
1 ANTIĆTIE DOWN Ć The PM requires that both buttons be
released if both were pressed and then one has been
released. There is no time delay for this condition to cause a
trip message. The PM also requires that once one button is
pressed, the other button needs to be pressed within 0.5
seconds to continue to operate without a problem.
2. Indication of change in the station active/bypass state or
nc/no contact wiring.
Check for proper wiring of station run buttons. Check for
proper operation of run button contacts.
