PD6600 Series Loop-Powered Process Meters
Instruction Manual

Solid State Relay Outputs (
RELAY
)
The meter can be optionally equipped with two solid
state relays that may be set up for alarms, timer,
stopwatch, or pump control. Alternatively, they may
be disabled.
Alarms are available based on the PV value or the
digital input. The alarm status will show on the display
even if the output is not wired.
Pump control allows the relay to turn on and off a
pump at specified on and off points. This can be done
using only one of the relays to control one pump (
ON-
OFF
) or using both relays in tandem to alternate
between two pumps (
ALTERN
).
A timer output (
TIMER
) turns the relay on and off at
the specified time intervals. The timer can be set as
single-shot or continuous timer.
The stopwatch output (
STPWATCH
) allows the relay to
be manually activated by starting the stopwatch. The
stopwatch count can be displayed on the top or
bottom display.
The output may be disabled by selecting
DISABLE
.
•
During setup, the relays do not follow the input
and they will remain in the state found prior to
entering the
Relay
menu.
Alarm (
ALARM
)
Alarm outputs may be assigned to the PV or the digi-
tal input. When assigned to the PV, the alarm may be
set as either a high alarm or a low alarm. Alarm ac-
tions (
AUTO
,
AUTO.MAN
,
LATCH
,
L-CLEAR
) determine
how and when the alarm should be reset. They oper-
ate as follows:
•
Automatic (
AUTO
):
Alarm will reset automat-
ically once the alarm condition has cleared.
•
Automatic/Manual (
AUTO.MAN
):
Alarm will
reset automatically once the alarm condition
has cleared but can also be reset using the
Enter
(ACK) button (or whichever function
key is set to acknowledge) at any time.
•
Latching (
LATCH
):
Alarm must be reset
manually and can be done so at any time.
Press the
Enter
(ACK) button at any time to clear the
alarm.
•
Latching with Reset after Clear (
L-CLEAR
):
Alarm must be reset manually and can only
be done so after the alarm condition has
cleared. Press the
Enter
(ACK) button after
the alarm condition has cleared to reset the
alarm.
If the alarm is set to PV, a set and reset point must be
programmed. The set point is the display value at
which the alarm will turn on and the reset point is the
display value at which the alarm will turn off. If the set
point is lower than the reset point, the alarm will be a
low alarm; if the set point is higher than the reset
point, the alarm will be a high alarm. The digital input
alarm will trigger whenever the digital input is trig-
gered.
For both the PV and digital input alarms, a delay be-
fore the alarm is turned on or off may be set, as well
as a fail-safe feature which reverses the on/off opera-
tion of the relays.
Alarm states will be displayed on the meter even if no
relay output is physically connected. These may in-
clude a red LED backlight, flashing PV value (PV
alarm only), and a programmable alarm message. In
addition, for meters without a bargraph an alarm indi-
cator (!) (only on meters with no bargraph) will also
display
.
