SAFETY This option is specifically designed to be used with the Optidrive HVAC variable speed drive product and is intended for professional incorporation into complete equipment or systems. If installed incorrectly it may present a safety hazard. The Optidrive HVAC uses high voltages and currents, carries a high level of stored electrical energy, and is used to control mechanical plant that may cause injury. Close attention is required to system design and electrical installation to avoid hazards in either normal operation or in the event of equipment malfunction. System design, installation, commissioning and maintenance must be carried out only by personnel who have the necessary training and experience. They must read carefully this safety information and the instructions in this Guide and follow all information regarding transport, storage, installation and use of the Option module, including the specified environmental limitations. Please read the SAFETY NOTICE carefully, and all Warning and Caution boxes elsewhere. CAUTION Store the Optidrive Option Module in its box until required. It should be stored in a clean and dry environment. Temperature range –40 o C to +60 o C. Install the Option Module into the Optidrive by inserting the module into the option module port of the Optidrive as shown in the mechanical installation section. Do not use undue force in inserting the option module into the port. WARNING Optidrives and the Option Modules should be installed only by qualified electrical persons and in accordance with local and national regulations and codes of practice. Electric shock hazard! Disconnect and ISOLATE the Optidrive before attempting any work on it. High voltages are present at the terminals and within the drive for up to 10 minutes after disconnection of the electrical supply. Where the electrical supply to the drive is through a plug and socket connector, do not disconnect until 10 minutes have elapsed after turning off the supply.

Option Module Slot Option Module OPTIDRIVE HVAC CASCADE OPERATION The Optidrive HVAC DOL Cascade control uses a maximum of three relays from the cascade option module and the 2 nd user relay from the standard drive terminals, giving the potential for 4 separate pumps under DOL control. The cascade option module is required if the system requires more than 1 DOL pump or when the 2 nd user relay on the drive is required for another function. The basic configuration for the drive and DOL pumps is shown below. In this configuration the 2 nd drive relay is used to control the first DOL pump with the cascade module controlling the remaining DOL pumps. In this configuration P2-18 must be set to 8 to configure the 2 nd drive relay for DOL pump control. P8-14 must be set to enable the DOL cascade function and P8-15 must be set with the number of pumps that make up the cascade system (from 1 to 4). The relays in the cascade module are assigned automatically starting with the lowest numbered relay. If the 2 nd relay is not assigned to DOL control then the configuration is as shown below and a maximum of 3 DOL pumps are permitted. For this configuration only parameters P8-14 and P8-15 need be set and the relays in the cascade module are assigned automatically starting with the lowest numbered relay. When cascade mode is enabled (P8-14 = 1) the relays contained on the cascade option module are dedicated to the cascade function and can only be used for other functions if P9-41 is set to 1 and relay functions are defined through the PLC logic using the OptiTools Studio software. LED STATUS INDICATION The cascade module has a Status LED – LED A (Green). LED A: Constant Green Indication - Modular is OK LED A: Flashing Green Indication – No Communication with drive LED A: LED Off In dication – No power to module LED B is not used.

Default (none cascade) functions are listed in the table below) Once the DOL cascade function is enabled (P8-14 = 1) the relays will assume DOL operation as detailed in the ‘Optidrive HVAC cascade operation’ section of this manual. Default Operation (DOL Cascade disabled, P8-14=0) Relay 3 Drive Healthy Indication (close on Healthy) Relay 4 Drive Fault Indication (close on fault) Relay 5 Drive Running Indication (close on enable) OPTIDRIVE HVAC PLC LOGIC OPERATION Relays on the HVAC Cascade Expansion module can be assigned functionality within the internal PLC logic (programmed via the OptiTools Studio software). In order to allow PLC configuration parameter P9-41 must be set to ‘1’ (user defined -PLC). When P9-41 is set to ‘1’ all default operation and cascade operation is automatically disabled and all extended relay function must be programmed through the PLC function.. See the OptiTools Studio software for further information.
