3-7 Input A Initial Delay
Range:
Function:
0 secs
*
[00:00 - 30:00
(min:secs)]
Sets a delay before an input trip can
occur. The initial delay is counted
from the time a start signal is
received. The state of the input is
ignored until the initial delay has
elapsed.
3-8 Remote Reset Logic
Option:
Function:
Selects whether the MCD 500's remote reset
input (terminals 25, 18) is normally open or
normally closed.
Normally Closed
*
Normally Open
7.7 Outputs

Option:
Function:
Selects the function of Relay A (normally
open).
Off
Relay A is not used
Main Contactor
*
The relay closes when the MCD 500 receives
a start command, and remains closed as long
as the motor is receiving voltage.
Run
The relay closes when the starter changes to
run state.
Trip
The relay closes when the starter trips.
Warning
The relay closes when the starter issues a
warning.
Low Current
Flag
The relay closes when the low current flag
activates (
4-10 Low Current Flag
).
High Current
Flag
The relay closes when the high current flag
activates (
4-11 High Current Flag
).
Motor Temp
Flag
The relay closes when the motor temperature
flag activates (
4-12 Motor Temperature Flag
).

The MCD 500 can be configured to wait before opening or
closing Relay A.
4-2 Relay A On Delay
Range:
Function:
0 secs
*
[0:00 - 5:00 (min:secs)] Sets the delay for closing Relay
A.
4-3 Relay A Off Delay
Range:
Function:
0 secs
*
[0:00 - 5:00 (min:secs)] Sets the delay for re-opening
Relay A.
7.7.2 Relays B and C
Parameters 4-4 to 4-9 configure the operation of Relays B

start command, and remains closed as long as
the motor is receiving voltage.
Run
*
The relay closes when the starter changes to
run state.
Trip
The relay closes when the starter trips.
Warning
The relay closes when the starter issues a
warning.
Low Current
Flag

B.
4-6 Relay B Off Delay
Range:
Function:
0 secs
*
[0:00 - 5:00 (min:secs)] Sets the delay for re-opening
Relay B.
4-7 Relay C Function
Option:
Function:
Selects the function of Relay C (normally
open).
Off
Relay C is not used
Main Contactor The relay closes when the MCD 500 receives a
start command, and remains closed as long as
the motor is receiving voltage.
