Enter the type of alarm function you wish to use Exclusive (Alarm switch is closed when the reported sensor value is outside of the low and high values selected.) or Inclusive (Alarm switch is closed when the reported sensor value is between the low and high values selected.).

Enter Output: A1 [1] or A2 [2]. Enter low threshold.

Enter high threshold.

Enter on delay in seconds [0-1200]. It is the time that the sensor value is in the alarm condition before the alarm switch activates.

Enter off delay in seconds [0-1200]. It is the time that the alarm switch drops out of the alarm condition before the alarm switch deactivates.

After entering this information the Setup menu reappears and to add additional alarms the process must be repeated.

Part B: Interfacing to the Alarm Circuit

An intermediate relay is recommended as the alarm interface to the device being controlled by the alarm. The intermediate relay provides isolation from any voltage or current spikes that might be associated with the device being controlled, e.g. a pump motor starting. Further, it is possible to use a programmable time relay in order to insure that the alarm does not go into a dithering state. A typical implementation is shown in Figure 11.

ALARMS

There are six user programmable alarms on the WMS-16.

 

They can be assigned to either of two alarm switches.

 

(ALARM 1 and ALARM 2) which provide a switched

 

connection to ground. Electrical connection is made to the

 

terminal strip at the positions labeled ALARM 1 and ALARM

 

2. The maximum current sinking capability of these switches

 

is 2amps.

Interfacing the WMS-16 with a Telephone Modem

The WMS-16 has a modem compatible firmware, which makes it possible to connect a standard telephone modem, with a speed capability of at least 9600 baud, between the WMS-16 and a telephone line so that the WMS-16 can be accessed remotely via telephone from a computer.

The serial cable from the WMS-16 is plugged into the modem. The modem at the WMS-16 is configured for auto answer and
