Field Configurable Ranges for Platinum, Nickel
and Copper RTDs
Ultra Slim Housing for High Density Installations
Description
The Ultra SlimPak G118 is a DIN rail mount, RTD input limit alarm
with dual setpoints and two contact closure outputs. The field
configurable input and alarm functions offer flexible setpoint
capability. There are up to eight temperature ranges available for
each RTD type to ensure accuracy and maximize setpoint resolution.
The G118 is configurable as a single or dual setpoint alarm, with
HI or LO trips and failsafe or non-failsafe operation. Also included
are adjustable deadbands (0.25 to 5% of full scale input) for each
setpoint and a flexible DC power supply which accepts any voltage
between 9 and 30VDC.
Diagnostic LEDS
The G118 is equipped with three front panel LEDs. The dual
function green LED is labeled INPUT and indicates line power and
input signal status. Active DC power is indicated by an illuminated
LED. If this LED is off, check DC power and the wiring connection.
If the input signal is more than 110% of the full scale range, the LED
will flash at 8 Hz. Below 0%, it flashes at 4 Hz. Two red LEDs indicate
the relay state for each setpoint. An illuminated red LED indicates
the tripped condition.

Dynamic Deadband
Circuitry in the G118 prevents false trips by repeatedly sampling
the input. The input must remain beyond the setpoint for 100
milliseconds, uninterrupted, to qualify as a valid trip condition.
Likewise, the input must fall outside the deadband and remain
there for 100 milliseconds to return the alarm to an untripped
condition. This results in a “dynamic deadband” (based on time)
in addition to the normal deadband.
Configuration
Unless otherwise specified, the factory presets the Model G118 as
follows:
Input:
Range: 0 to 250°C
Output: Dual, SPDT
Failsafe: No
Deadband: A, B: 1.0%
The DC power input accepts any DC source between 9 and 30V;
typically a 12V or 24VDC source is used (see Accessories).
Platinum (100 Ohm)
Trip: A:HI, B:LO
Output
The G118 is equipped with two SPDT (form C) relays, rated at
120VAC or 28VDC at 5 Amperes. Each of these relays is independently controlled by the field configurable setpoint and
deadband.
Operation
The field configurable G118 limit alarm setpoints can be configured for HI or LO, failsafe or non-failsafe operation. Each of the
setpoints has a respective HI or LO deadband. In a tripped
condition, the setpoint is exceeded and the appropriate red LED
will illuminate. The trip will reset only when the process falls below
the HI deadband or rises above the LO deadband (see Figure 1).
For proper deadband operation the HI setpoint must always be set
above the LO setpoint. In failsafe operation, the relay is energized
when the process is below the HI setpoint or above the LO setpoint
(opposite for non-failsafe). In the failsafe mode, a power failure
results in an alarm state output.
For other I/O ranges, refer to Tables 1 through 3 and reconfigure
switches SW1 and SW2 for the desired input type, range and function.
WARNING: Do not change switch settings with power applied.
Severe damage will result!
1. With DC power off, position input switches 1 through 6 on
“SW2” for RTD type (Table 1).
2. Set position 1 through 4 of input range switch “SW1” for the
desired RTD type and input temperature range (Table 3).
3. Set position 5 and 6 of input range switch “SW1” to ON for a HI
trip setpoint or OFF for a LO trip setpoint (Figure 4).
4. Set position 7 of input range switch “SW1” to ON for non-failsafe
operation or OFF for failsafe operation (e.g. alarm trips upon
power failure).

Calibration
1. After configuring the DIP switches, connect the input to a
calibrated RTD source or a resistance decade box and apply power.
Note: To maximize thermal stability, final calibration should be
performed in the operating installation, allowing approximately 1
to 2 hours for warm up and thermal equilibrium of the system.
2. Setpoint Calibration: Before adjusting the setpoint, adjust the
deadband pot to its minimum (fully counterclockwise). With the
desired trip RTD resistance input applied, adjust the setpoint pot
until the relay trips. For HI trip calibration, start with the setpoint
pot above the desired trip (fully clockwise). For LO trip
calibration, start with the setpoint pot below the desired trip (fully
counterclockwise).
Relay Protection & EMI Suppression
When switching inductive loads, maximum relay life and transient
EMI suppression is achieved using external protection (see Figures
2 and 3). Place all protection devices directly across the load and
minimize all lead lengths. For AC inductive loads, place a properly
rated MOV across the load in parallel with a series RC snubber. Use
a 0.01 to 0.1uF pulse film capacitor (foil polypropylene recommended) of sufficient voltage, and a 47 ohm, 1/2W carbon
resistor. For DC inductive loads, place a diode across the load (PRV
> DC supply, 1N4006 recommended) with (+) to cathode and (-) to
anode (the RC snubber is an optional enhancement).

Figure 3: AC Inductive Loads
3. Deadband Calibration: Set the deadband pot to its minimum
(fully counterclockwise). Adjust the setpoint pot to the desired
trip. Adjust the RTD resistance input until the relay trips. Readjust
the deadband pots to 5% (fully clockwise). Set th RTD resistance
input to the desired deadband position. Slowly adjust deadband
(counterclockwise) until the relay untrips.
