1.1General information and part numbers

●This supplementary information does not replace the comprehensive Operating Instructions!

●Equipment may only be installed by qualified electrical personnel in compliance with the applicable accident prevention regulations and the MOVITRAC® Operating Instructions.

The power ratings of the MOVITRAC®31C...-503-4-01 special version for crane control are the same as those of the standard version and can be taken from the MOVITRAC® 31C Operating Instructions.

Part numbers of the special version for crane control:

1.2Differences to the MOVITRAC® 31C basic version

MOVITRAC® 31C...-503-4-01 inverters are especially equipped for applications such as trolleys for bridge cranes and hoists.

● Two operating modes are implemented.

The signal level on input TL. 34/35 determines which of the two operating modes is active:

TL. 34	0...5 V	= “0"	motorized potentiometer mode	(ground control)
	7.5...30 V	= ”1"	fixed setpoint mode	(radio control)
TL. 35	jumper with TL. 30 (0V24)

●A comprehensive limit switch control monitors the preliminary and ultimate (operational) limit switches along the distance of travel of the bridge crane or trolley. To this end, the binary inputs TL. 48/49/50/51 are permanently assigned to limit switch monitoring (low active). Parameters P603...P606 are therefore ineffective.

●External fault detection via TL. 36/37:

The analogue input is used for an “external fault” binary input signal, which is active when low.

TL. 36	0...5 V	= “0"	external fault
	7.5...30 V	= ”1"	no fault
TL. 37	jumper to TL. 30
Note:	If this signal input is not used, then TL. 36 - TL. 44 (+24V) and TL. 37 - TL. 30 must
	be jumpered

●The following functions of the standard version are no longer available:

-manual operation (P 87_)

-master/slave operation (P 88_)

-setpoint n1 TL. 32/33 with standard function

-setpoint n2 TL. 34/35

-external current limit TL. 36/37

-programming capability of the binary inputs TL. 42-51 (P 60_)

-all functions, activated through binary inputs Exception: fixed setpoints

parameter set selection

-reset via binary input

Terminals X14:48 - X8:48 and X14:49 - X8:49 are OR’d internally, allowing terminals X14:48-49 or X8:48-49 to be used alternatively.

An external voltage +24V can be applied directly to analogue inputs X2:34 and X7:36. The negative output of the external power supply must be connected to 0V24 (TL. 30).

If not all limit switch inputs (TL. 48/49/50/51) are used, the open inputs must be connected to +24V (TL. 44) as otherwise the limit switch monitoring will signal a fault (→ Sec. 2.6 Fault signals).

1.6Limit switch connection

The use of end-of-track limit switches for crane control is supported. Altogether four limit switch inputs are available for monitoring the travel and the travel speed. ( → Sec. 1.4 Wiring diagram and Sec. 1.5 Control inputs).

- CW ultimate limit switch		TL. 48
- CW preliminary limit switch		TL. 49
-	CCW ultimate limit switch	TL. 50
-	CCW preliminary limit switch	TL. 51

The limit switches must be installed along the distance of travel in accordance with Fig. 4. For safety reasons the limit switches must be implemented as “low active”. When the inverter is enabled the internal limit switch monitoring feature monitors whether both preliminary and ultimate limit switches are connected in accordance with the wiring diagram (→ Sec. 1.4). If only one of the two preliminary or ultimate limit switches is missing no fault signal is issued. The limit switches are not monitored for correct connection.

If not all limit switch inputs (TL. 48/49/50/51) are used, the open inputs must be connected to +24V (TL. 44) otherwise the limit switch monitoring will issue a fault signal (→ Sec. 2.6 Fault signals).
