6.9.5 Programming the Dry Contacts and the Clock
The Alpha FXM’s front panel contacts (C1 to C6) can be programmed to meet your specifications with RS–232
communications. You can also adjust the Alpha FXM’s date and time.
Programming the Dry Contacts
The functions of dry contacts C1 to C5 (and if factory configured, dry contact C6) can be changed with RS-232
communications.
For example, to change contact C1:
1. To see how it is currently programmed, type c1 (all lower case) and press Enter.
2. The Alpha FXM responds with *c1=1 where the * shows the unit responded to your command.
For example: a "1" shows it is programmed to be the On Battery indicator as shown in the Dry Contact
Configuration table below.
Table L — Dry Contact Conguration
1= On Batt ery 4= Alarm 7= Timer 2
2= Low Battery 5= Fault 8= Timer 3
3= Timer 1 6= Disabl ed 9= 48 VDC
(Only available for contact C6)
3. To change the contact, type c1=X where X is 1 to 9 and press Enter.
The Alpha FXM responds with *c1=(1 to 9). The programming is done for that contact. Repeat as necessary
for the other contacts.
Each contact can only be programmed for one function at a time and cannot show multiple conditions.
4. To reset the contacts to the factory default, type d efault and press Enter. The Alpha FXM responds with
*default, showing it is reset. This command also resets the timer setting to the 2 hours factory default. See
“Setting the Timer Contact”. See "Specifications" for the factory default settings of dry contacts C1 to C6.
