HMI Bypass Controller Installation and Commissioning Guide 49
6.3 VFD Parameter Access
The HVAC Drive H300 VFD parameters settings required
for operation in a bypass system are set at the factory.
Adjustments can be made to VFD parameters via the HMI
for all standard applications. If there is a need to access
advanced parameters not accessible via the HMI there are
2 methods available:
1. Remove the HVAC Drive H300 keypad cover and plug in
a keypad, order code
HOA-KEYPAD-RTC . For a complete list of parameters go
to www.controltechniques.com
2. Connect a PC to the SI-ETHERNET module
in the drive and use
“Connect” software to
access parameters. This software is available
as a no charge download from www.
controltechniques.com
In order to successfully connect to the drive
via the SI-ETHERNET module the PC
Ethernet IP address needs to be set to
192.168.0.xxx where xxx is not = 010 and
the subnet mask needs to be 255.255.255.0.
WARNING
CAUTION : Changes made to VFD parameters may result in unintended motor
operation and damage to equipment.
6.4 VFD Replacement
If the VFD has to be replaced, it is
recommended that the SI-ETHERNET module
in the existing drive is re-used and fitted to
the replacement drive. If a new SI-ETHERNET
MODULE is needed, order code
HMI-BYP-SI-
ETHERNET is pre-configured at the factory
for HVAC Drive H300 HMI Bypass settings. If
a new SI-ETHERNET module is fitted it is necessary to set the IP address of
the module to 192.168.0.010 and the subnet mask to 255.255.255.0. A VFD
keypad or Connect software is required to set the address.
