Page 3: Installation
INSTALLATION Mount the controller Mount the controller on a 35 mm DIN rail. The physical dimensions of the controller is: 86 x 160 x 60 mm (3.39 x 6.30 x 2.36 inch) (H x W x D). If it doesn’t easily snap onto the rail, you can pull the small tab at the bottom side of the unit, using a small screwdriver. -

Recommendation is to use external relays together with a flyback diode to each relay according to figure.
- Page 8 CHECK YOUR INSTALLATION After the installation, there are possibilities to check the status of the digital and analog in- and outputs in the menus of EC 531. This could be used for validations of the installation and for fault tracking.

Page 9: Communication Ports
AquaProg. Select Modbus RTU or TCP and Modbus ID in settings. Cross reference table is available. First time a PC connects to EC 531, a wizard appears at the screen. Just follow the instructions on your PC. - Page 10 3.5.1 Communication parameters RS 485 The EC 531 can act as a slave or master in the RS 485 network. If EC 531 is set as master, all the surrounding units must be set as slaves. All the units in the RS 485 network must be using the same communication parameters; baud rate, parity and stop bits.

Page 18: How To Clean The Unit
Power off the unit. Only outside / front shall be cleaned by using a dry, soft cloth. A good choice would be the microfiber type of cloth. Gently wipe the EC 531 front in order not to scratch the overlay. If the dry cloth did not completely remove the dirt, do not press harder in an attempt to scrub it off. - Page 20 Sulzer Pump Solutions Ireland Ltd., Clonard Road, Wexford, Ireland Tel. +353 53 91 63 200, Fax +353 53 91 42 335, www.sulzer.com Copyright © Sulzer Ltd 2018...
