Termination
Table 1:
TerminationTable
* [CH3] and [CH4] are referenced to [GND] if (CG) is selected at time of order. [CH3] and [CH4] are referenced to each other if (DF) is selected at time of order.
** S1-4, Position (CG) connects [Temp-] terminal to the [GND] terminal internally. The (DF) position makes the [TEMP -] terminal floating. (See Fig.10)
*** This is the current output of the solid state sensor and must be configured as S1-4 set to (DF) to allow the 592 or 334 sensor to operate.
^ The reed contact to override [CH4] can be set up for (CG) which shorts the [CH4] output to [GND] or (DF) shorting the output terminals [CH3/CH4].
^^ The E-POT controls the output resistance setpoint and during override, the E-POT controls the resistance to <100 ohms for 3-5 seconds.
^^^ A reed dry contact across the sensor [TEMP+/-] is configured at time of order as a (-61) option.
~ The [TEMP] terminals are used for an external 10K-2 thermistor connection if the [EXT option] is selected. (wire=25’ max)

(see Table 2,

BAPI recommends
using twisted pair of at least 22 AWG. Larger gauge wire may be required for long runs. All wiring
must comply with the National Electric Code (NEC) and local codes.
Do NOT
run this device’s wiring in the same conduit
as AC power wiring of NEC class 1, NEC class 2, NEC class 3 or with wiring used to supply highly inductive loads such
as motors, contactors and relays. BAPI’s tests show that fluctuating and inaccurate signal levels are possible when AC
power wiring is present in the same conduit as the signal lines.

Terminal Notes: (Related to table 1), [ ] = Terminal designation
1. Only one variable and output type per channel. [CH3] and [CH4] can be
overridden.
2. The [GND] terminal is always the reference for [V+], [CH1] and [CH2]
terminals.
3. The temperature output range is limited to between 32º to 158ºF
(0º to 70ºC).
4. Humidity setpoint range is limited between 0 to 100% RH.
5. The override is available on [CH3], [CH4] and [TEMP+/TEMP-] only.
6. Voltage outputs are limited to between 0 to 10 VDC and are only
referenced to [GND].
7. Current outputs are limited to between 0 to 20 mA and are only refer-
enced to [GND].
8. Resistive E-POT outputs are limited to a 1K, 10K, 50K or 100K
W
linier
POT, ±30%.
9. Resistive sensor [TEMP+/TEMP-] outputs may be any BAPI passive or
solid state sensor.
10. When using a 592/334 sensor, [TEMP+] is the supply (5 to 30 VDC)
[TEMP-] is the current output to the analog input @ 1µA/ºC and requires
S1-4 to be set for (DF). Reversal of the power will damage the sensor.
11. The Test and Balance option (-TB) cannot be used with the 592/334 sen-
sor.
12. If the BAPI-Stat has the external sensor option (-EXT), then it must be a
10K-2 thermistor purchased separately. The external sensor is wired to
the temp + and temp - terminals. A humidity signal or passive sensor are
not allowed in this configuration.
