rL
, relay mode, determines how the relay works. The available modes
are explained in the table and the figure below. Please refer to section 5.3 for
details of program-sections.

ALAM
ALAM
Relay activated by temperature alarms, which are
determined by parameter AH, AL, DH, and DL.
1.1
BEEP
BEEP
Relay is synchronized with on-board buzzer.
1.2
ALBE
ALBE
Relay activated by temperature alarms. The on-board
buzzer also beeps when temperature alarms are
triggered.
1.3
RAMP
RAMP Relay activated during ramp-up and ramp-down
sections.
1.4
HEAT
HEAT
Relay activated during the ramp-up sections only.
1.5
COOL
COOL
Relay activated during the ramp-down sections only.
1.6
STEP
STEP
Relay activated during the step section only, i.e., timer-
counting sections.
1.7
EXTN
EXTN
Relay activated during the extended-steps, which
includes the ramp section and the step section.
1.8
Note 1.1
ALAM
, temperature alarm, the relay will be activated when the alarm
conditions defined by AH, AL, DH, or DL are met.
Note 1.2
BEEP
. The relay is synchronized with the on-board event buzzer. The
on-board buzzer goes off when an event happens, which are start of a program,
end of a step, start of a step-timer, end of a program, pause of a step-timer, and
resume of a step-timer.
Here is a special case. If a relay’s, for example Relay 1,
rL1
is set to
BEEP
and
the other relay’s mode
rL2
is set to
ALBE
, that means the on-board buzzer will
go off whenever the temperature alarms are triggered Relay 2 alarm settings,
hence the Relay 1 will also pull-in as the buzzer goes off. When the on-buzzer is
triggered by temperature alarms, the user can mute the buzzer by pressing the
RUN key. Once the buzzer is muted, the Relay 1 will also drop out.
Note 1.3
ALBE
, both the relay and the on-board buzzer will be activated when
the temperature alarm conditions are met.
Note 1.4
RAMP
. Relay will be activated during RAMP sections, i.e., the transition
sections when the previous step has ended and before the next step starts. A
ramp section is essentially a section between two steps when step-timer isn’t
counting time.
Note 1.5
HEAT
. Relay will be activated during the HEAT sections, i.e., ramp
sections where heating is needed.
Note 1.6
COOL
. Relay will be activated during the COOL sections, i.e., ramp
sections where cooling is needed.
Note 1.7
STEP
. Relay will be activated during the STEP sections, i.e., when
step-timer has been started and has not yet ended.
Note 1.8
EXTN
. Relay will be active during Extended Step section, which include
a STEP and its RAMP section.
Note 2
.
rRG
, relay range, defines whether this relay works in MASH program
only, BOIL program only, or in all programs. This parameter can be set to
MASH
,
BOIL
, and
ALL
. By default, it is set to
ALL
.
Note 3
.
LGC
, relay logic, determines relay status before and after the alarm
conditions are met. It can be set to Logic-Close (
RL-C
) or Logic-Open (
RL-O
).
When a relay is set to
RL-C
, the relay is a normally open (NO) relay, i.e., the relay
stays open when it is inactive; the relay pulls in (close) when it is activated. When
a relay is set to
RL-O
, the relay is essentially a normally closed (NC) relay, i.e., it
stays closed when it is inactive; the relay contacts open up (drop out) when the
relay is activated. By default,
LGC
= RL-C, which should be used for most
applications.
Note 4
.
rLP
, relay programming, is a parameter that determines at which steps in
a program the relay is allowed to function per its relay mode (
rL
, see note 1 in
this section) setting. This parameter has a numeric value ranging from 0 to 511,
where “0” means the relay is not allowed to function at any step in a program,
and “511” means the relay is enabled for all 9 steps in a program. Any other
value in between 0 and 511 indicates that the relay is only allowed to function at
certain specified steps. The calculation method is explained later in this section.
Two special codes,
NONE
and
ALON
, are added to the
rLP
values, where
“
NONE
” is equivalent to “0”, and “
ALON
” is equivalent to “511”. By default,
rLP
= ALON, which allow the relay functioning for the entire program.
To use this feature, the user should decide at which steps the relay is enabled,
and then use the equation below to calculate the value of
rLP
:
rLP
= A×1 + B×2 + C×4 + D×8 + E×16 + F×32 + G×64 + H×128 + I×256,
where the letter A, B, C, and etc. are binary numbers, 0 or 1, representing
whether the relay function is allowed at a particular step. The Table 17 shows the
letter code, the code value, and the multiplier of each step. For instance, if the
user wants to enable the relay function only at step 1 and 5, the
rLP
value should
be 17 (
rLP
= A×1 + E×16 = 1×1 + 1×16 = 17). The value of
rLP
can be
calculated by this online relay programming calculator
here
.
