7. Operating Mode
Mode A:

Page | - 4 -© Page | - 4 - © Copyright Mastip Technology Limited. Information subject to alteration. V2.0 www.mastip.com
Sequential Injection Controller SC8
1) When the controller receives the injection signal (t1), delay time begins.
2) The controller counts down the delay time and displays it on DEL display unit.
3) At the end of delay time, the controller opens the gate output, counts the open time and
shows it on OPEN display unit.
4) The controller keeps the gate output open until the injection signal is off (t2).
5) When the injection signal is off, the controller resets the delay time and shows it on DEL
display unit. And the counted open time is showed on OPEN display unit until the next
injection signal comes on.
6) If the injection signal is off before the delay time passed, the controller will reset the delay
time and wait for the next injection signal.
Mode B:
1) When the controller receives the injection signal (t1), delay time begins
2) The controller counts down the delay time and displays it on DEL display unit.
3) At the end of delay time, the controller opens the gate output, counts the open time and
shows it on OPEN display unit.
4) At the end of open time, the controller closes the gate output.
5) When the injection signal is off (t2), the controller resets the delay time & open time, and
shows them on DEL & OPEN display units.
6) If the injection signal is off before the delay time passed, the controller will reset the delay

time and wait for the next injection signal.
7) If the injection signal is off before the open time passed, the controller will close the gate
output, and reset the delay time & open time.
Mode AB:
1) When the controller receives the injection signal (t1), the indicator A is lit up and delay
time1 begins.
2) The controller counts down the delay time1 and displays it on DEL display unit.
3) At the end of delay time1, the controller opens the gate output, counts the open time1 and
shows it on OPEN display unit.
4) At the end of open time1, the controller closes the gate output.
5) Then the indicator B is lit up and delay time2 begins.
6) At the end of delay time2, the controller opens the gate output, counts the open time2 and
shows it on OPEN display unit.
7) At the end of open time2, the controller closes the gate output.
8) When the injection signal is off (t2), the controller resets the delay time & open time, and
shows delay time 1 & open time 1 on DEL & OPEN display units.
9) If the injection signal is off before the delay time1 passed, the controller will reset the
delay time and wait for the next injection signal.
10)If the injection signal is off before the open time1 passed, the controller will close the gate
output, and reset the delay time and open time.
11) If the injection signal is off before the delay time2 passed, the controller will reset the
delay time and open time, then wait for the next injection signal.
12) If the injection signal is off before the open time2 passed, the controller will close the
gate output, and reset the delay time and open time.
