DO NOT add the service factor of themotor into the setting. A service factor of 1.2 xFLA is designed into the overload.• Pressing the test pushbutton verifies theoperation of the overload. The overload shouldtrip when pressed. Use the reset pushbutton toreset the overload after test.• Reset is used to reset the overload after it trips. Ifthe overload is still hot, wait until the motorreaches normal operating temperature beforeresetting. The overload offers a manual (hand) orauto reset selection. It is highly recommended tooperate in the manual factory setting to preventthe risk of damage to the motor.6.1.12 ECB Safety InterlockGeneral informationThe safety interlock feature prevents the drive or bypassfrom operating. Only a fire mode command to runoverrides this function. For operation in drive or bypassmode, the safety external interlock input contact must beclosed. External inputs include, but are not limited to, highand low pressure limit switches, fire alarm, smoke alarm,high and low temperature switches, and vibration sensors.OperationWhen an external safety input closes on ECB terminals 1and 2 on connector X57, the option panel is in operationalmode. When open, power to the motor is disabled. Thebypass ignores all run commands except for fire modeoperation, when applicable. The drive display indicatesalarm 221, bypass interlock, meaning the problem isexternal to the drive. A factory installed jumper betweenX57 terminals 1 and 2 allows the unit to operate when nosafety input is connected. This jumper must be removedwhen connecting in a safety interlock circuit.Safety interlock function setup• Remove factory-installed jumper between ECBconnector X57 terminals 1 and 2 on drive controlterminals.• Wire safety input to connector X57 terminals 1and 2.• For technicians familiar with connecting to driveterminals 12 and 27 for safety interlock, be awarethat ECB bypass operation will NOT stop with theexternal fault report. Use terminals 1 and 2 onconnector X57, as indicated, for bypass control.6.1.13 ECB Common Run/StopGeneral informationThe common run/stop function provides remote run andstop control of the motor(s) while in either drive or bypass.Without common run/stop, the motor would automaticallyrun at full speed whenever the bypass is activated. Theremote signal provides drive control as well as bypasscontrol, making this one input common to both. Commonrun/stop is enabled by factory default. When used with therun permissive function, common run/stop permits runrequest operation in bypass.OperationA user supplied remote run command wired to driveterminals 13 and 18 initiates remote drive or bypassoperation. Common run/stop can also be activated byhand on the LCP or through serial communication.Operation in either drive or bypass is determined by driveor bypass mode selection, not the run/stop command.Before enabling common run/stop• Complete the start-up procedure to verify motorrotation direction in bypass is correct and thatthe system is ready in all respects for continuousfull speed operation in bypass.Common run/stop setup• Wire a remote run/stop to drive input terminals13 and 18 (default run input). Ensure thatparameter 18 is programmed for run (defaultsetting).6.1.14 ECB Advanced Fire ModeGeneral informationDrive operation in advanced fire mode is programmable. Inthe event the drive does not function, the motor isoperated in bypass at full speed. Fire mode is intended toignore common safety and overload inputs in emergencysituations. The fire mode function is built-in. See the drivesupport materials for programmable options.Electronically Controlled B...
