EN 60603-2 (DIN 41612) type D standard and designated as follows: X1 and X2, and X3 and X4 – the latter pair serves as intrinsically safe outputs (Fig. 2). The PMB-2 relay is installed by sliding it into a matching installation unit with pre-installed connectors to match the output slots in the back of the PMB-2. -

11 Operating principle of the controller 11.1 Starting the product Whenever the PMB-2 is powered on, it enters a self-test routine to verify its components, in- cluding the internal memory, the supply voltage, internal temperature, operation of actuator relays and the current trip measurement lines. If the self-test routine detects an fault in the operation of any of the components, the product switches to the FAILURE status. -
Page 23: Ready
Operation Manual no. BP/IO/01/16 ed. 1.0.1 11.2.2 Ready In the READY status, the PMB-2 awaits the „Start” command to switch on the outlet. 11.2.3 Signal Some applications require the main contactor is made (switched on) with a certain delay or with a preceding warning signal. -
Page 24: Self-Test
Operation Manual no. BP/IO/01/16 ed. 1.0.1 11.2.8 Self-test Whenever the PMB-2 relay is powered on, it starts a self-test routine to check the current trip lines . This status is indicated with the AUTOTEST message on the display. During the self- test, the measurement inputs for both outlets of the product are isolated from the external lines connected to slot X2. -

This option applies to two-speed motors with galvanically bonded winding packs, like in the Danhlander system. In this configuration, the current trips are operated by a single set of current transformers in both speeds and a single earth leakage trip, overtemperature trip, etc… PMB-2 Page 33... - Page 34 – If this checkbox is ticked, the 2nd speed will be switched to by an external input signal connected to the PMB-2. In this case the user must con- trol the delay time after the 1st speed is enabled or acknowdledged as enabled and the maximum current threshold which triggers the 2nd speed.

The time set using the „Stop Time” setting also includes any duration of the warning signal. Thanks to this, the total downtime is equal to the value of the „Stop Time” setting. On the other hand, the countdown on the display is reduced by the duration of the warning signal. PMB-2 Page 37... -
