Specifications

MCD3000 Series

10 MG.15.A4.22 - VLT is a registered Danfoss trademark

Installation

Par. Set input. If there is an open circuit the primary

parameters (Par. 1 - 9) are operative. If there is a

closed circuit the secondary parameters (Par. 25 - 33)

are operative.

The MCD3000 provides three relay outputs.

All outputs are programmable. Refer Par. 36, 37 & 38

Relay Function Assignment.

■

Motor thermistors

If the motor is fitted with thermistors these may be

connected directly to the MCD3000. A trip will occur if

the thermistor circuit resistance is above

approximately 2.8k

Ω.

If thermistors are not connected to the MCD3000

there must be a link across the thermistor input

terminals.

Control circuit examples

Example 1. A basic installation where motor operation

is controlled using the MCD3000 Local Control Panel.

Notes:

1. The MCD3000 must be in local mode to function

with this circuit. Use the [LOCAL/REMOTE] push

button to switch between local and remote

modes.
