SAFETY FUNCTIONS
7.4 WARNING function setting
The WARNING functions can be set to Enable or Disable. Set to "ENABLE" when using the
WARNING function. Set to "DISABLE" to release each WARNING function after the WARNING is
detected.
A setting value of the "Pump Run Time Over" and "Pump Overload" are adjustable. The WARNING
detection can be released by setting the value larger than pump running hours after "Pump Run Time
Over" is detected. Also, the WARNING detection can be released by powering off the pump after
"Pump Overload" is detected.
See Table 47 and Table 48 for the default setting. The setting can be changed via serial
communication, the STP-Link (optional accessory) or the display unit iDT-001 (optional accessory).
