Parameter Definition
OUT1ALG
The
OUTPUT ALGORITHM
lets you select the type of
output you want.
ATTENTION
If the recorder has two controllers
(both enabled), OUT1ALG applies for controller #1 and
OUT2ALG applies for controller #2.
Selections are model dependent. For example, current
output models cannot be configured for Time
Proportioning Simplex Output.
TIME
RELAY SIMPLEX
— type of output using one SPDT
relay. Its normally open (NO) or normally closed (NC)
contacts are selected by positioning an internal jumper.
Other prompts affected: "OUT HYST"
Controller #1 uses Relay 3 and overrides control of
relay by Alarm 3. Controller #2 uses Relay 5 and
overrides control of relay by Alarm 5.
CURRNT
CURRENT SIMPLEX
— type of output using one 4 to
20 mA signal that can be fed into a positive or negative
grounded load of 0 to 1000 ohms. The signal can be
recalibrated for any desired range from 3.25 to 21 mA
for 0 to 100% output.
POSITN
POSITION PROPORTIONAL SIMPLEX
— type of
output using two SPDT relays and a motor which has a
100 to 1000 ohms feedback slidewire.
Other prompt affected: "DEADBAND"
Controller #1 uses Relays 3 and 4 and overrides
control of relays by Alarms 3 and 4. Controller #2
uses Relays 5 and 6 and overrides control of relays
by Alarms 5 and 6.
TIME D
RELAY DUPLEX
— type of output using two SPDT
relays. Its normally open (NO) or normally closed (NC)
contacts are selected by positioning an internal jumper
(see Installation section).
Other prompts affected: "DEADBAND"
Controller #1 uses Relays 3 and 4 and overrides
control of relays by Alarms 3 and 4. Controller #2
uses Relays 5 and 6 and overrides control of relays
by Alarms 5 and 6.
CUR TI
CURRENT/RELAY DUPLEX (RELAY = HEAT)
is a
variation of duplex with current active for 0 to 50%
output (tuning set 2) and relay active for 50 to 100%
output (tuning set 1).
Other prompts affected: "4-20 RNG," "DEADBAND"
Controller #1 uses Relay 3 and overrides control of
relay by Alarm 3. Controller #2 uses Relay 5 and
overrides control of relay by Alarm 5.
