4.7.4 Synchronized Press Operation
SYNC: Synchronized Press Signal
For using multiple numbers of press units, connect parallel with SYNC common.
Multiple Press Synchronized Sequence
At the start of the cycle until reaching the synchronization point (1
ST
Load), the SYNC signal is
ON (LOW condition) to stop other Units from continuing to the second step.
When the 1
st
load is reached, the signal works as an input signal (Wired OR). If it reads LOW -
meaning that the other units have not reached 1
ST
Load yet - the unit stays in the standby state
waiting for all connected presses to reach 1
ST
Load. When the SYNC signal is HIGH (all units
have completed the first step), all units simultaneously start the second step.
If a unit is in bypass mode, its SYNC signal stays off (High Condition) to prevent the other units
from being in a waiting condition.
The SYNC signal stays ON (LOW) in the following conditions:
