Safety and Precautions - Use Contrac power electronics EAS 822, EBS 852, and EBS 862 for driving the Contrac actuators specified on the electronics ID label, only. - Prior to maintenance or repair works always disconnect the electronics from mains and secure the respective control actuator against reactive process forces. -
Page 5: General
The electronic unit is designed for rail-mounting in a special rack providing four mounting levels. Either four units (EAS822 and / or EBS852) or one unit (EBS862) can be installed on each level. It is also pos- sible to mix the units, as seen in figure 5. Do not transport the rack with the units installed; the total weight is too high. - Page 6 5.1.2 EBS 862 1 PG cable gland for mains connection 2 PG cable gland for motor connection 3 PG cable glands for signal connection 4 Cover screws 5 Hinge screws 6 Commissioning and service field (CSF) d0112rxa Fig. 2: On the electronics side, the power supply and the motor cable are connected via screw terminals, and the signal cables are connected via an internal plug and socket connection.

Page 23: Setup
13.Setup The actuator only requires the basic settings (adaptation to the operating range) in order to be operated with the standard or custumer specific configuration. Use the Local Control Panel (LCP) for these set- tings. Use the appropriate configuration software for more detailed parameter changes or diagnosis functions. -
Page 24: Adjustment Using The Configuration Program
13.1.4Setting 13.1.4.1 “Setting” mode - Set electronics to “setting” mode by pressing both push buttons (3) simultaneously for approx. 5 seconds, until both LEDs (2 + 8) are flashing synchronously at approx. 4Hz. („setting mode“ is the standard electronic unit status after passing the final factory test) 13.1.4.2 Defining first position (0% or 100%) (Higher precision in 2nd position) - Move to desired position by pressing one of the push buttons (3). -
