over the dFSP, the process will be automatically stopped until you reset the

system (please refer figure 4 to reset).

Note 14. Distilling Ending Option: dEO.

When the timer counting ends, or when the distill finishing temperature is

reached, the controller will generate six long beeps. The top display will switch

between the current temperature and "End" alternately. After the process ends,

the power output can be configured either to continue heating, or shut off. This

is controlled ending options, dEO. Set it to ON for continue heating, set it to

OFF to turn off the output.

If you want to use the timer as a regular timer without correlating to the

temperature setting, you can set dFSP below the ambient temperature (or just

zero). The timer will start as soon as the regulator is powered up. You can use

the reset button (rSt) to reset the timer at any time.

7. External Relay Settings

7.1 Introductory

This controller contains two normally open (N.O.) relays that can be used for

controlling external devices such as buzzers, contactors, and valves. The relays

are dry switches that can handle a 3 Amps of resistive loads or a 1 Amp of

inductive loads. These relays can be programmed as process (absolute) alarms,

deviation alarms, or act in synchronization with the controller's timer as well as

the acceleration phase. There are a few advanced features of these relays. The

action of a relay can be synchronized with alarm conditions, can be a single

pulse for a pre-determined time duration, or can be latched action that can only

be turned off by human intervention. The relays can be set either to close the

contacts, or to open the contacts when alarm condition meets. In addition,

Relay 1 (AL1) can be set to act in synchronization with the acceleration heating

phase of the main control output. This feature enables the user to control

external contactors and so to employ extra heating elements during acceleration

phase. The Relay 2 (AL2) can be set to act in synchronization with the timer for

mashing or boiling/distilling. User can use this Relay 2 to drive an external

indicator or a valve that need to be turn on when the time is up.

Parameters for configuring relays are divided into two groups. The first group of

parameters is for determining the functions of relays. They are nested under the

system configuration settings (see Table 4). Once they are set for a particular

application, there is no need to change them. The second group of parameters

is for alarm on/off temperatures and alarm durations. These parameters are

nested under alarm configuration settings (see Table 7).

7.2 Relay related parameters in system settings

In the menu for system settings, there are five pairs of parameters for configuring

relays.

Note 15.: RL (Relay Mode), determines which mode a relay should be working

at. RL1 is for Relay 1 and RL2 is for Relay 2. Each relay has three modes.

Process Alarm Mode (Pr) (also called Absolute Alarm) and Deviation Alarm

Mode (De) are available for both Relay 1 and Relay 2. In addition, Acceleration

Mode (Acc), which set the relay to synchronize with the acceleration phase of

the main control output for the SSR, is only available to Relay 1. Timer Mode

(Time), which set the relay to synchronize with the timer function, is only

available to Relay 2.

When a relay is set as a Process Alarm, it can either be triggered by a process

high alarm, by a process low alarm, or by both.

When a relay is set as a Deviation Alarm, it can be triggered by a deviation high

alarm, by a deviation low alarm, or by both. Deviation alarms are only available
