1. Wiring
2. Depending on whether [voltage input] or [non voltage input], connect the wiring as shown below.
Input/Output for External Control
3. Depending on whether [voltage input] or [non voltage input], connect the wiring as shown below.
Input with Voltage.
Set the Voltage/Non voltage changeover switch (SS1) to VOLT.
Input with No Voltage.
Set the Voltage/Non voltage changeover switch (SS1) to NON VOLT.
4. Display Signal Retrieval (Output)
The normal operation output terminals (W1, W2) and error output terminals (W3, W4) are non-voltage output contacts.
(Permissive current is 10mA~3A per contact.)
Output is as given below.
