Brown 1) The sensors are connected by a dedicated lead wire (ZS-38-5L (for master and one slave) or ZS-38-U (for master and up to 1 slaves)). Copying is performed through a dedicated communication line. 2) Select the slave switch which is to be the master, and change it into a master using the buttons. (In the default setting, all switches are set as slaves.) 3) Press the button of the master switch to start copying. Formula for Obtaining the Set-Value P_1 or P_2 P_1 (P_2) = A (A-B)/4 n_1 (n_2) = B (A-B)/4 Master-side sensor ZS-38-U Brown: DC Blue: DC (DC, DC, and wires are connected among connectors.)

When the buttons are simultaneously pressed for 1 second or longer, while holding, the held value will be reset. E Keylock function Prevents operation errors such as accidentally changing setting values. F Zero-clear function This function clears and resets the zero value on the display of measured.

G Error indication function Error name Error code Description Action Overcurrent error current of 8 ma or more is applied to the switch output (OUT1). current of 8 ma or more is applied to the switch output (OUT2). Eliminate the cause of the over current by turning off the power supply, and then turn on it again. Residual error During zero-clear operation, over ±7% F.S. is applied. (ZSE3AF (compound) ±3.5% F.S.) After 1 second, the mode will reset to measurement mode. ±1% F.S. of the zero-clear range varies between individual products. Perform zero-clear operation again after restoring the applied to an atmospheric condition. Applied error Supply exceeds the maximum set. Supply is below the minimum set. Reset applied to a level within the set range. System error Internal data error Turn off the power supply and then turn on it again. If the failure cannot be solved, please contact SMC for investigation. If the failure cannot be solved after the above instructions are performed, please contact SMC for investigation. H Anti-chattering function (F3) A large bore cylinder or ejector consumes a large volume of air in operation and may experience a temporary drop in the supply. This function prevents detection of such temporary drops in the supply as an error. Available response time settings 2 ms, 1 ms, 5 ms, 1 ms, 2 ms <Principle> This function averages values measured during the response time set by the user and then compares the average value with the set point value to output the result on the switch.
