Horner APG HE693CALKIT simulation module

Horner APG HE693CALKIT simulation module

Product Introduction

（1） Product Features

Horner APG HE693CALKIT calibration software is a computer program designed to support on-site and factory calibration of specific Horner APG simulation modules.

（2） Package composition

Each set includes: a floppy disk with calibration software, an RS-232 9-pin serial cable, a TTL to RS-232 converter, and an RS-232 ribbon cable with a 10 pin plug.

（3） Software operation requirements

Operating environment: Requires running on an IBM or compatible computer using DOS 3.1 or higher.

Hardware requirements: A text display is required and a serial port (COM1 or COM2) is used. The program defaults to using COM1.

（4） Module connection and preparation

The simulation module needs to be connected to the selected serial port on the computer through an RS-232 cable, combined with a TTL-to-RS-232 converter or an RS-232 ribbon cable with a 10 pin plug (depending on the simulation module to be calibrated).

The module does not need to be configured in the PLC, but appropriate power must be provided for the bus pins of the module.

Set conditions

（1） General Requirements (2.1)

Module installation: The module to be calibrated must be inserted into the PLC it will be used in the application; When inserting, the PLC must be powered off. After the module is correctly inserted into the PLC rack, the rack should be installed vertically (see Figure 1) to ensure good ventilation of the module; The PLC must be in 'stop' mode.

Stabilization time: After inserting the module into the PLC and completing the calibration connection, it needs to stabilize for at least 15 minutes after power on to ensure appropriate temperature balance.

Environmental requirements: Do not expose any equipment involved in the module or calibration process to extreme temperature changes; Calibration can be performed using an expansion rack.

（2） Set up process (2.2)

No additional special steps are required, and it should be carried out in conjunction with equipment preparation and module specific conditions.

（3） Equipment Requirements (2.3)

Calibrator: High quality calibrators (such as Omega CL511) must be used, and their accuracy must be more than twice that of the module (for example, THM884 has an accuracy of ± 1 degree Celsius, and the calibrator accuracy must be at least ± 0.5 degrees Celsius); It is recommended that all Horner Electric simulation modules use battery powered calibrators. When calibrating any thermocouple module, a battery powered calibrator must be used.

Wire requirements: The wire used for calibration must be the same as the wire used in the application, and must be of high quality with the shortest possible length; Avoid exposing wires to excessive radio frequency (RF) or electromagnetic interference (EMI) during the calibration process to prevent introducing errors.

（4） Module specific conditions (2.4)

1. Analog input module (2.4.1)

Covering HE693ADC406, HE693ADC405, HE693ADC415, HE693ADC410, HE693ADC420, the general requirements are as follows:

Calibrator: More than twice the accuracy of the module and powered by batteries.

Wire: Use high-quality wire that is the same as the wire used in the application and has the shortest length.

Environment: Avoid exposing the module to excessive EMI or RF, extreme temperature changes.

Installation and status: The module needs to be inserted into the PLC slot used in the application, and after being powered on and connected, it should be stable for at least 15 minutes. It should be installed vertically (in the panel installation position), and the PLC should be in "stop" mode; The unused channels during the calibration process of HE693ADC406 need to be short circuited and grounded.

2. Analog output module (2.4.2)

Regarding HE693DAC410 and HE693DAC420, it is required to be consistent with the analog input module (except for the channel short-circuit grounding of HE693ADC406).

3. Resistance Temperature Detector (RTD) module (2.4.3)

Including HE693RTD600, HE693RTD601, HE693RTD660, HE693RTD665, HE693RTD666, in addition to meeting the general requirements of the analog input module, there are additional requirements: unused channels during calibration must be short circuited and grounded; Modules with a suffix of -20 need to use the a=d switch (PT100D) in the calibration software.

4. Strain gauge module (2.4.4)

Including HE693STG883 and HE693STG884, it is required to be consistent with the RTD module (without using channel short-circuit grounding).

5. Thermocouple module (2.4.5)

Covering multiple models such as HE697THM160 and HE693THM166, in addition to meeting the general requirements for analog input modules, there are additional requirements: modules with a suffix of -21 need to use external ISOBLK for cold end compensation; During the calibration process, the last channel needs to be short circuited and grounded to optimize cold end compensation; Modules with suffix -02 need to use the "=k" switch in the executable file (refer to section 4.1).

Calibration process

（1） General Instructions (3.1)

The general calibration process is only a basic framework, with slight differences in the calibration process of each module, but the core logic is consistent. The simulation module needs to be calibrated according to the specific process described in the subsequent sections; Table 3.1 lists the simulation modules and their corresponding calibration files, with some corresponding relationships as follows:
