Error Messages
The SMMC-3 will display an error message whenever a problem is
detected with the connection to the SMTS-1 or any of the SMPS-
1’s. Note that the connection status to a gutter (SMGS-1) or aerial
(SMAS-1) sensor is not monitored by the SMMC-3.
SMTS-1 Error
Manual only <M1>
Error!- SMTS-1 <cancel>
SMPS-1 Error
Error!- SMPS-1
<cancel>
The error screen will flash intermittently with the standard
operating screen. To cancel the error message press the
DOWN button when the error screen is showing.
If there is a SMTS-1 error all automatic operation of the
SMMC-3 ceases, however manual operation of each zone is
still possible.
If there is an SMPS-1 error, automatic control of the
associated zone is suspended, again manual operation is still
possible. Once the sensor problem has been fixed turn off the
power to the SMMC-3 Control Panel at the toggle switch,
reconnect the sensor wiring to the terminal block, then after a
minimum 10 seconds turn back on the power. The SMMC-3
program will recognize the sensor and begin normal
operation.
