6.1.13 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 emergency
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 programming 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 the
command is removed or the unit fails.
•
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.

6.1.14 ECB Fault Reporting

General Information
The ECB monitors bypass contactors M2 and M3 and
reports failures to the drive for display and external
reporting. The drive also monitors the ECB card for bypass
communication errors.
Operation
ECB detected faults are reported by the drive in three
ways: Warnings and alarms are displayed on the keypad
display, through serial communication, or through output
relays. The drive provides a form-C fault relay on terminals
01, 02, and 03. The fault contacts are fail-safe, meaning
that if power is removed the contacts close and a fault
condition is reported.

Electronically Controlled Bypass (ECB) Opera-
The drive monitors the ECB card communication and
detects when communication stops. An ECB card failure or
communication error could cause this. Contact Trane using
the phone number on the back of this manual for
technical support if this happens. The phone number can
also be found on the label inside the panel cover.
Fault Reporting Function Setup
•
Automatic function. No set up required.
