Ecb Common Run/Stop - Trane TR200 Operating Instructions Manual

ECB Common Run/Stop

General Information
The common run/stop function provides remote run and stop control of the motor(s) while in either drive or
bypass. Without common run/stop, the motor would automatically run at full speed whenever the bypass is
activated. The remote signal provides drive control as well as bypass control, making this one input common
to both. Common run/stop is enabled by factory default. When used with the run permissive function, common
run/stop permits run request operation in bypass.
Operation
A user supplied remote run command wired to drive terminals 13 and 18 initiates remote drive or bypass op-
eration. Common run/stop can also be activated by hand on the drive keypad or through serial communication.
Operation in either drive or bypass is determined by drive or bypass mode selection, not the run/stop command.
Prior to Enabling Common Run/Stop
• Complete the start-up procedure to verify motor rotation direction in bypass is correct and that the
system is ready in all respects for continuous full speed operation in bypass.
Common Run/Stop Setup
• Wire a remote run/stop to drive input terminals 13 and 18 (default run input). Ensure that parameter 18
is programmed for run (default setting).
ECB Advanced Fire Mode
General Information
Drive operation in advanced fire mode is programmable. In the event the drive does not function, the motor is
operated in bypass at full speed. Fire mode is intended to ignore common safety and overload inputs in emer-
gency situations. The fire mode function is built-in. See the drive support materials for programmable options.
Prior to Enabling Fire Mode
• Complete the start-up procedure to verify motor rotation direction in bypass is correct and that the
system is ready in all respects for continuous full speed operation in bypass.
• Verify that the drive is programmed for the fire mode function. See the drive support materials for pro-
gramming the fire mode function.
Operation
• Activation of fire mode is accomplished by programming the drive for fire mode.
• When activated, the ECB ignores safety circuits and motor overload.
• Fire mode is deactivated only when removed or fuses blow.
• Fire mode status can be reported through serial communications or drive output.
Fire Mode Function Setup
• Program drive for fire mode.
• If required, program a drive output for fire mode status.
• See the drive support materials for programming the fire mode function.
ECB Fault Reporting
General Information
The ECB monitors bypass contactors M2 and M3 and reports failures to the drive for display and external re-
porting. The drive also monitors the ECB card for bypass communication errors.
