IMPROPER TIME DELAY USE
•
Always use time delay module connected to non safety related machine operation and use safety control modules as e-
stop, door, two-hand control to immediately stop dangerous motion.
•
Never use a time delay when the machine reaction time is not consistent in this case use a standstill monitor control
module FF-SR05936.
•
The FF-SRT module time delay value must be selected or adjusted to be greater than the time necessary to stop the
hazardous machine motion for both regular and emergency stop conditions (includes power removal).
Failure to comply with these instructions could result in death or serious injury.
MODULE CONTACTS DAMAGE
Use arc suppressors across the coil of the safety relays K1, K2, K4, K5 and K6 to increase the life of the modules.
Failure to comply with these instructions will result in product damage.
The cable resistance between S11-S12 and S21-S22 of the FF-SRS5935 e-stop module must be less than 68 Ohms for
correct operation of the module.
