6. Optional Additional Relay Connections

a. TTSIM-1A units have a built in Form-C alarm relay that can be configured to indicate LEAK; LEAK or TROUBLE; or LEAK,

SERVICE NEEDED or TROUBLE. The access to these individual relays is via Terminals 10,11 and 12 on each installed

TTSIM-1A unit, see below.

b. The ADAM-4069 module has 8 relays. The first three of these are pre-assigned for buzzer control, summary LEAK and

summary TROUBLE. The fourth relay is a watchdog contact that switches to the alarm position if the ADAM-4069 fails to

detect communications activity on the RS-485 external device buss. (Lack of activity indicates loss of power or a frozen

computer).

The remaining 4 relays are available as user programmable relays (see H80760 Operation Manual for set-up options and

details). Physical connections to the relays are made at the ADAM-4069 module

i. Remove the ADAM-4522 by loosening two screws and temporarily disconnecting the RS232 connector.
