12 HVAC Drive H300
Issue Number: 3
Real time clock
• An internal real time clock is available which is used for the timer functions and trip log.
Timer functions
• Two timers are available to switch an output on a routine basis.
Sleep / Wake mode
• Sleep / wake mode stops and starts the motor during periods of low demand to improve system efficiency.
Advanced Process PID
• Two PIDs are available which can operate independently or combine to provide more complex functionality.
RTD's
• A PT1000 RTD temperature sensor input is available which can directly provide an analog input without a transducer for control of fans and
pumps.
2.3 Model number
The way in which the model numbers for the HVAC Drive H300 range are formed is illustrated below:
Figure 2-2 Model number
* Only shown on Frame 9 and above identification label.
** For further information on the D, C or T power format models, please refer to the Modular Installation Guide
For simplicity, a Frame 9 drive with no internal choke (i.e. model 09xxxxxxE) is referred to as a Frame 9E and a Frame 9 drive with an internal choke
(i.e. model 09xxxxxxA) is referred to as a Frame 9A. Any reference to Frame 9 is applicable to both sizes 9E and 9A. All Frame 10 and 11 drives are
supplied with no internal choke.
Fire Mode - Important Warning
When Fire Mode is active the motor overload and thermal protection are disabled, as well as a number of drive protection functions. Fire
Mode is provided for use only in emergency situations where the safety risk from disabling protection is less than the risk from the drive
tripping - typically in smoke extraction operation to permit evacuation of a building. The use of Fire Mode itself causes a risk of fire from
overloading of the motor or drive, so it must only be used after careful consideration of the balance of risks.
Care must be taken to prevent inadvertent activation or de-activation of Fire Mode. Fire Mode is indicated by a flashing display text
warning "Fire mode active".
Care must be taken to ensure that parameters Pr 01.053 or Pr 01.054 are not inadvertently re-allocated to different inputs or variables. It
should be noted that, by default, Pr 01.054 is controlled from digital input 4 and or Pr 08.024 can re-allocate this digital input to another
parameter. These parameters are at access level 2 in order to minimize the risk of inadvertent or unauthorized changes. It is recommended
that User Security be applied to further reduce the risk (see section 5.9.1 User Security Level / Access Level on page 117). These
parameters may also be changed via serial communications so adequate precautions should be taken if this functionality is utilized.
