(3). Connecting Alarm Setpoint Outputs (Non-valtage Contacts)
The maximum wire length is 100 m. However, since the use of long wires makes the device susceptible to noise, using wires no more
than 10 m long is recommended.
CAUTION
• To use X1 relay, obtain one that satisfies the following specifications.
Operating coil
[Applied load]
MAX: 24 VDC, 5 W (Built-in diode)
MIN: 5 VDC, 2 mW (Built-in diode)
*1 AC loads cannot be connected.
*2 Provide a power supply (V1, V2) that matches the load and relay to be used.
• To drive a direct load, use ones within the following.
[Applied load]
MAX: 24 VDC, 5 W
MIN: 5 VDC, 2 mW
* AC loads cannot be connected.
• Make sure that the copper wiring is not short-circuiting the plates (cover, lower case) or neighboring wires.
• Perform wiring so that the terminal block is not strained.
If strained, use a wire guide or junction terminal to alleviate the stress on the terminal block.
• Do not connect the wires directly from the top of the control panel to the terminal block.
Moisture may enter this device along the wiring and cause electric shock or fire.
* The contact of the internal relay is always ON
during detection of an upper/lower limit alarm.
