9.7.4  Programming the Dry Contacts

The Alpha Micro 100 front panel contacts (C1 and C2) can be programmed to meet your specifications. Each con-
tact can only be programmed for one function at a time and cannot show multiple conditions.
The functions of dry contacts can be changed with HyperTerminal. For example, to change contact C2:
To see how it is currently programmed, type 

c2

 (all lower case) and press 

Enter

.

The Alpha Micro 100 responds with 

*c2=2

 where the 

*

 shows the unit responded to your command. 

For example: a "

2

" shows it is programmed to be the 

Low Battery

 indicator.

To change the contact, type 

c2=X

 where X is 1 to 14 and press 

Enter

.  

The Alpha Micro 100 responds with 

*c2=(1 to 14)

. For example, to change the C2 contact to be the Temperature 

indicator, type 

c2=11

Table Q  —  Dry Contact Configuration Settings

1= On Battery

Used for remote indication of the On Battery condition.

2= Low Battery

Used for remote indication of the Low Battery condition.

3= Timer 1

See "Setting the Timer Contact" on page 68.

4= Alarm

Used for remote indication of an Alarm condition.

5= Fault

Used for remote indication of a Fault condition.

6= Disabled

Dry contact is disabled, i.e. never energizes.

7= Timer 2

See "Setting the Timer Contact" on page 68.

8= Timer 3

See "Setting the Timer Contact" on page 68.

9= External Vdc

Not available on Micro 100.

10= Generator

Reserved for future use.

11= Temperature

Not available on Micro 100.

12= Low Battery, Shutdown

Contact will activate when battery is low (factory-defined level) and the unit is running in 

Inverter mode. Contact is deactivated when battery level returns to an acceptable value.

13= Low Battery and Line

Used for remote indication that the battery is low in Line mode. This condition can be 
used to interpret the health of the battery.

14= LVD (Low Voltage 
Disconnect)

The dry contact is energized when the battery voltage is greater than the LVD 
CONNECT set voltage (see "Control Parameters" on page 32) and will de-energize if 
the battery voltage drops below 21V. 

15= Output Relay

The dry contact is used for energizing external output relay. The external AC contactor 

can be controlled for disconnect/reconnect by configuring one of the dry contacts as 

Output Relay. Output relay option is built-in for Micro 100.

Caution:

 On 230Vac models, any relay when configured to “Output relay” is wrongly 

triggered during transitions to and from Boost 1 and Boost 2 modes while in AVR 
Reduced mode.
